+L'extension \pkg{nicematrix} est entièrement contenue dans le fichier |nicematrix.sty|. Ce fichier peut être placé

+avec une distribution TeX comme MiKTeX ou TeXlive.

+\bigskip
+Cette extension peut être utilisée avec |xelatex|, |lualatex| et |pdflatex| mais aussi avec le cheminement

+
+\bigskip
+Cette extension nécessite et charge les extensions \pkg{l3keys2e}, \pkg{xparse}, \pkg{array}, \pkg{amsmath} et
+\pkg{pgfcore} ainsi que le module \pkg{shapes} de \textsc{pgf} (l'extension \pkg{tikz}, qui est une surcouche de

+
+
+\bigskip
+L'idée de \pkg{nicematrix} est de créer des nœuds \textsc{pgf} derrière les cases et les positions des filets des
+tableaux créés par \pkg{array} et de les utiliser pour développer de nouvelles fonctionnalités. Comme toujours avec
+\textsc{pgf}, les coordonnées de ces nœuds sont écrites dans le fichier |.aux| pour être utilisées à la
+compilation suivante. C'est pourquoi l'utilisation de \pkg{nicematrix} nécessite \textbf{plusieurs compilations
+ successives}.
+
+\bigskip
+La plupart des fonctionnalités de \pkg{nicematrix} sont accessibles sans avoir à utiliser explicitement
+\textsc{pgf} ou Tikz (ce dernier n'est d'ailleurs pas chargé par défaut).
+
+\bigskip
Une commande|\NiceMatrixOptions| est fournie pour régler les options (la portée des options fixées par cette
-commande est le groupe TeX courant).
+commande est le groupe TeX courant : elles sont semi-globales).

+\newpage
+
+\section{Les environnements de cette extension}
+
+L'extension \pkg{nicematrix} définit les nouveaux environnements suivants :
+
+\medskip
+\begin{ttfamily}
+\setlength{\tabcolsep}{3mm}
+\begin{tabular}{llll}
+\{NiceTabular\} & \{NiceArray\} & \{NiceMatrix\} \\
+ & \{pNiceArray\} & \{pNiceMatrix\} \\
+ & \{bNiceArray\} & \{bNiceMatrix\} \\
+ & \{BNiceArray\} & \{BNiceMatrix\} \\
+ & \{vNiceArray\} & \{vNiceMatrix\} \\
+ & \{VNiceArray\} & \{VNiceMatrix\}
+\end{tabular}
+\end{ttfamily}
+
+
+\medskip
+Les environnements |{NiceArray}| et |{NiceTabular}| sont similaires aux environnements |{array}| et |{tabular}| de
+l'extension \pkg{array} (qui est chargée par \pkg{nicematrix}).
+
+\medskip
+Il y a néanmoins quelques différences :
+\begin{itemize}
+\item Pour des raisons techniques, dans le préambule de ces environnements, l'utilisateur doit utiliser les lettres
+|L|, |C| et~|R|\footnote{Les types de colonnes |L|, |C| et |R| sont définis localement à l'intérieur de
+ |{NiceTabular}| ou |{NiceArray}| avec la commande |\newcolumntype| de \pkg{array}. Cette définition masque une
+ éventuelle définition précédente.} au lieu de |l|, |c| et |r|, y compris dans les commandes |\multicolumn| et
+dans les types de colonnes définis par |\newcolumntype|.
+
+\item Dans |{NiceArray}| (et ses variantes), les colonnes de type |w| (ex. : |wc{1cm}|) sont composées en mode
+mathématique alors que dans |{array}| de \pkg{array}, elles sont composées en mode texte.
+\end{itemize}
+
+\medskip
+Les environnements |{pNiceArray}|, |{bNiceArray}|, etc. n'ont pas d'équivalents dans \pkg{array}.
+
+\medskip
+Les environnements |{NiceMatrix}|, |{pNiceMatrix}|, etc. sont similaires aux environnements correspondants de
+l'\pkg{amsmath} (qui est chargée par \pkg{nicematrix}) : |{matrix}|, |{pmatrix}|, etc.
+
+\medskip
+Tous les environnements de l'extension \pkg{nicematrix} acceptent, entre crochets, une liste optionnelle de paires
+de la forme \textsl{clé=valeur}. {\bfseries Il doit n'y avoir aucun espace devant le crochet ouvrant (|[|) de cette
+liste d'options.}
+
+
+
+\section{L'espace vertical entre les rangées}
+
+Il est bien connu que certaines rangées des tableaux créés par défault avec LaTeX sont trop proches l'une de
+l'autre. On en donne ci-dessous un exemple classique.
+
+\medskip
+\begin{BVerbatim}[baseline=c,boxwidth=9cm]
+$\begin{pmatrix}
+\frac12 & -\frac12 \\
+\frac13 & \frac14 \\
+\end{pmatrix}$
+\end{BVerbatim}
+$\begin{pmatrix}
+\frac12 & -\frac12 \\
+\frac13 & \frac14 \\
+\end{pmatrix}$
+
\bigskip
-\textbf{Un exemple d'utilisation pour les lignes en pointillés continues}
+En s'inspirant de l'extension \pkg{cellspace} qui traite de ce problème, l'extension \pkg{nicematrix} propose deux
+clés |cell-space-top-limit| et |cell-space-bottom-limit| qui sont similaires aux deux paramètres
+|\cellspacetoplimit| et |\cellspacebottomlimit| proposés par \pkg{cellspace}. La valeur initiale de ces paramètres
+est $0$~pt pour que les environnements de \pkg{nicematrix} aient par défaut le même comportement que ceux de
+\pkg{array} et de l'\pkg{amsmth} mais une valeur de $1$~pt serait un bon choix. On conseille de régler leurs
+valeurs avec la commande |\NiceMatrixOptions|.
\medskip
-\begin{minipage}{10cm}
-Considérons par exemple le code suivant qui utilise un environnement |{pmatrix}| de l'extension \pkg{amsmath}.
+\begin{Verbatim}
+\NiceMatrixOptions{~emphase#cell-space-top-limit = 1pt,cell-space-bottom-limit = 1pt@}
+\end{Verbatim}
+\begin{BVerbatim}[baseline=c,boxwidth=9cm]
+$\begin{pNiceMatrix}
+\frac12 & -\frac12 \\
+\frac13 & \frac14 \\
+\end{pNiceMatrix}$
+\end{BVerbatim}

+ cell-space-top-limit = 1pt ,
+ cell-space-bottom-limit = 1pt ,
+}
+$\begin{pNiceMatrix}
+\frac12 & -\frac12 \\
+\frac13 & \frac14 \\
+\end{pNiceMatrix}$
+\end{scope}
+
+
+\bigskip
+\section{La clé baseline}
+
+L'extension \pkg{nicematrix} propose une option |baseline| pour la position verticale des tableaux. Cette
+option |baseline| prend comme valeur un entier qui indique le numéro de rangée dont la ligne de base servira de
+ligne de base pour le tableau.
+
+\medskip
+\begin{BVerbatim}[baseline=c,boxwidth=9cm]
+$A = \begin{pNiceMatrix}[~emphase#baseline=2@]
+\frac{1}{\sqrt{1+p^2}} & p & 1-p \\
+1 & 1 & 1 \\
+1 & p & 1+p
+\end{pNiceMatrix}$
+\end{BVerbatim}
+$A = \begin{pNiceMatrix}[baseline=2]
+\frac{1}{\sqrt{1+p^2}} & p & 1-p \\
+1 & 1 & 1 \\
+1 & p & 1+p
+\end{pNiceMatrix}$
+
+
+\interitem
+L'option |baseline| peut aussi prendre les trois valeurs spéciales |t|, |c| et |b|. Ces trois lettres peuvent aussi
+être utilisées de manière absolue comme pour l'option des environnements |{tabular}| et |{array}| de \pkg{array}.
+La valeur initiale de |baseline| est~|c|.
+
+
+\bigskip
+Dans l'exemple suivant, on utilise l'option |t| (synonyme de |baseline=t|) immédiatement après un |\item| de liste.
+On remarquera que la présence d'un |\hline| initial n'empêche pas l'alignement sur la ligne de base de la première
+rangée (avec |{tabular}| ou |{array}| de \pkg{array}, il faut utiliser |\firsthline|\footnote{On peut aussi utiliser |\firsthline|
+ dans les environnements de \pkg{nicematrix}.}).

+\end{enumerate}
+\end{minipage}
+\section{Les blocs}
+\label{Block}
+Dans les environnements de \pkg{nicematrix}, on peut utiliser la commande |\Block| pour placer un élément au centre
+d'un rectangle de cases fusionnées. La commande |\Block| ne crée pas d'espace par elle-même.
+
+La commande |\Block| doit être utilisée dans la case supérieure gauche du bloc avec deux arguments. Le premier
+argument est la taille de ce bloc avec la syntaxe $i$-$j$ où $i$ est le nombre de rangées et $j$ le nombre de
+colonnes du bloc. Le deuxième argument, est, sans surprise, le contenu du bloc.
+
+Dans |{NiceTabular}|, le contenu est composé en mode texte. Dans les autres environnements, il est composé en mode
+mathématique.
+
+\medskip

+\end{NiceTabular}
+\end{center}
+
+
+
\bigskip
+On peut aussi utiliser la commande |\Block| dans des matrices mathématiques.
+
+\medskip
+\begin{BVerbatim}[baseline=c,boxwidth=10.6cm]
+$\begin{bNiceArray}{CCC|C}[margin]
+~emphase#\Block{3-3}{A}@ & & & 0 \\

+& \hspace*{1cm} & & \Vdots \\
+& & & 0 \\
+\hline
+0 & \Cdots& 0 & 0
+\end{bNiceArray}$
+
+\bigskip
+On peut souhaiter agrandir la taille du «$A$» placé dans le bloc de l'exemple précédent. Comme il est composé en
+mode mathématique, on ne peut pas directement utiliser une commande comme |\large|, |\Large| ou |\LARGE|. C'est
+pourquoi une option à mettre entre chevrons est proposée par |\Block| pour spécifier du code LaTeX qui sera inséré
+\emph{avant} le début du mode mathématique.
+
+\medskip
+\begin{BVerbatim}[baseline=c,boxwidth=10.6cm]
+$\begin{bNiceArray}{CCC|C}[margin]
+\Block{3-3}~emphase#<\LARGE>@{A} & & & 0 \\
+& \hspace*{1cm} & & \Vdots \\

+& \hspace*{1cm} & & \Vdots \\
+& & & 0 \\
+\hline
+0 & \Cdots& 0 & 0
+\end{bNiceArray}$
+
+
+\section{Les filets horizontaux et verticaux}
+
+Les techniques habituelles pour tracer des filets peuvent être utilisées dans les environnements de
+\pkg{nicematrix}, à l'exception de |\vline|.
+
+\subsection{L'épaisseur et la couleur des filets}
+
+Les environnements de \pkg{nicematrix} proposent une clé |rules/width| pour fixer la largeur (en fait l'épaisseur)
+des filets dans l'environnement. En fait, cette clé ne fait que fixer la valeur de |\arrayrulewidth|.
+
+\smallskip
+On sait que \pkg{colortbl} propose la commande |\arrayrulecolor| pour spécifier la couleur de ces filets.
+
+\smallskip
+Avec \pkg{nicematrix}, il est possible de spécifier une couleur même si \pkg{colortbl} n'est pas chargé. Par souci
+de compatibilité, la commande est nommée également |\arrayrulecolor|. Les environnements de \pkg{nicematrix}
+proposent également une clé |rules/color| qui permet de fixer cette couleur pour l'environnement en question.
+
+\medskip
\begin{scope}
-\NiceMatrixOptions{transparent}
-\begin{minipage}{10cm}
-Maintenant, si nous utilisons l'extension \pkg{nicematrix} avec l'option |transparent|, le même code va donner le
-résultat ci-contre à droite.

-1 & \cdots & \cdots & 1 \\
-0 & \ddots & & \vdots \\
-\vdots & \ddots & \ddots & \vdots \\
-0 & \cdots & 0 & 1
-\end{pmatrix}$
+\hfuzz=10cm
+\begin{BVerbatim}[baseline=c,boxwidth=9.5cm]

+\hline
+rose & tulipe & lys \\
+arum & iris & violette \\
+muguet & dahlia & souci \\
+\hline
+\end{NiceTabular}
\end{scope}
+\medskip
+Si on veut définir de nouveaux spécificateurs de colonnes pour des filets (par exemple plus épais ou bien d'une
+couleur spécifique), on aura peut-être intérêt à utiliser la commande |\OnlyMainNiceMatrix| décrite p.~\pageref{OnlyMainNiceMatrix}.
-\section{Les environnements de cette extension}
+\bigskip
+\subsection{Une remarque concernant \textbackslash cline}
-L'extension \pkg{nicematrix} définit les nouveaux environnements suivants :
+\label{remark-cline}
+Les traits verticaux et horizontaux que l'on insère avec |\hline| et le spécificateur de colonne «\verb+|+» de
+\pkg{array} rendent le tableau plus large ou plus long d'une quantité égale à la largeur du trait.
+
+\smallskip
+Pour des raisons historiques, il n'en est pas de même pour la commande |\cline|, comme on peut le voir avec
+l'exemple suivant.
+
\medskip
-\begin{ttfamily}
-\setlength{\tabcolsep}{3mm}
-\begin{tabular}{llll}
-\{NiceMatrix\} & \{NiceArray\} & \{NiceTabular\} \\
-\{pNiceMatrix\} & \{pNiceArray\} \\
-\{bNiceMatrix\} & \{bNiceArray\} \\
-\{BNiceMatrix\} & \{BNiceArray\} \\
-\{vNiceMatrix\} & \{vNiceArray\} \\
-\{VNiceMatrix\} & \{VNiceArray\} \\
- & \{NiceArrayWithDelims\}
+\begin{BVerbatim}[baseline=c,boxwidth=10cm]
+\setlength{\arrayrulewidth}{2pt}
+\begin{tabular}{cccc} \hline

+\cline{2-2}

+\hline
+\end{tabular}
+\end{scope}
+\medskip
+Dans les environnements de \pkg{nicematrix}, cette situation est corrigée (il est néanmoins possible de revenir au
+comportement par défaut de |\cline| avec la clé |standard-cline|).
\medskip
-Par défaut, les environnements |{NiceMatrix}|, |{pNiceMatrix}|, |{bNiceMatrix}|, |{BNiceMatrix}|, |{vNiceMatrix}|
-et |{VNiceMatrix}| se comportent quasiment comme les environnements correspondants de \pkg{amsmath} : |{matrix}|,
-|{pmatrix}|, |{bmatrix}|, |{Bmatrix}|, |{vmatrix}| et |{Vmatrix}|.

+\end{NiceTabular}
+\end{scope}
+\bigskip
+\subsection{Les clés hlines et vlines}
+
+La clé |hlines| demande un tracé de tous les filets horizontaux et la clé |vlines| demande un tracé de tous les
+filets verticaux. En fait, dans les environnements avec délimiteurs (comme |{pNiceMatrix}| ou |{bNiceArray}|), les
+filets extérieurs ne sont pas tracés (ce qui est le comportement certainement attendu).
+
+
\medskip
-Les environnements |{NiceArray}| et |{NiceTabular}| sont similaires aux environnements |{array}| et |{tabular}| de
-l'extension |{array}|. Néanmoins, pour des raisons techniques, dans le préambule de ces environnements,
-l'utilisateur doit utiliser les lettres |L|, |C| et~|R| au lieu de |l|, |c| et |r|. Il est possible d'utiliser les
-constructions |p{...}|, |m{...}|, |b{...}|, |w{...}{...}|, |W{...}{...}|, \verb+|+, |>{...}|, |<{...}|, |@{...}|,
-|!{...}| et |*{n}{...}|.

+Il y a néanmoins une différence entre l'utilisation de l'option |vlines| et du spécificateur «\verb+|+» dans le
+préambule de l'environnement : les filets tracés par |vlines| traversent les double-filets horizontaux tracés par
+|\hline\hline| (il n'y a pas besoin d'utiliser \pkg{hhline}).

+La clé |hvlines| demande le tracé de tous les filets horizontaux et verticaux \emph{sauf dans les
+ blocs}.\footnote{En fait, quand la clé |hvlines| est utilisée, les filets ne sont pas non plus tracés dans les blocs virtuels

+La commande |\diagbox| (inspirée par l'extension \pkg{diagbox}) permet, quand elle est utilisée dans une case, de

+\subsection{Filets en pointillés}
+
+
+Dans les environnements de \pkg{nicematrix}, il est possible d'utiliser la commande |\hdottedline| (fournie
+par \pkg{nicematrix}) qui est l'équivalent pour les pointillés des commandes |\hline| et |\hdashline|
+(cette dernière étant une commande de \pkg{arydshln}).

+\end{pNiceMatrix}$
+
+
+\bigskip
+Dans les environnements avec un préambule explicite (comme |{NiceTabular}|, |{NiceArray}|, etc.), il est possible
+de dessiner un trait vertical en pointillés avec le spécificateur «|:|».

+\end{pNiceArray}$
+
+\bigskip
+Il est possible de changer dans \pkg{nicematrix} la lettre utilisée pour indiquer dans le préambule un trait
+vertical en pointillés avec l'option |letter-for-dotted-lines| disponible dans |\NiceMatrixOptions|.
+
+
+\bigskip
+\emph{Remarque} : Quand l'extension \pkg{array} (sur laquelle s'appuie \pkg{nicematrix}) est chargée, les traits
+verticaux et horizontaux que l'on insère rendent le tableau plus large ou plus long d'une quantité égale à la
+largeur du trait\footnote{En fait, cela est vrai pour |\hline| et «\verb+|+» mais pas pour |\cline|.}. Avec
+\pkg{nicematrix}, les lignes en pointillés tracées par |\hdottedline| et «|:|» ont le même effet.

+\section{Les couleurs des rangées et des colonnes}
+
+L'extension \pkg{colortbl} permet de colorier des cases, des rangées ou des colonnes d'un tableau. Néanmoins,
+l'affichage du \textsc{pdf} résultant n'est pas toujours parfait, en particulier quand on utilise également des
+filets. Dans certains lecteurs de \textsc{pdf}, des filets verticaux semblent disparaître. De fines lignes blanches
+peuvent également apparaître.
+
+\medskip
+L'extension \pkg{nicematrix} propose des outils similaires qui ne présentent pas ces inconvénients. Elle propose
+une clé |code-before|\footnote{Il existe aussi une clé |code-after| : cf. p.~\pageref{code-after}.} pour du code
+qui sera exécuté \emph{avant} le tracé du tableau. Dans ce |code-before|, de nouvelles commandes sont disponibles :
+|\cellcolor|, |\rectanglecolor|, |\rowcolor|, |\columncolor|, |\rowcolors| et |\chessboardcolors|.
+\label{code-before}
+
+\medskip
+Ces outils sont indépendants de \pkg{colortbl}.\footnote{On peut donc colorier les filets, les cellules, les
+ rangées, les colonnes, etc. sans charger \pkg{colortbl}. Le présent document ne charge pas \pkg{colortbl}.}
+
+\medskip
+Toutes ces commandes acceptent un argument optionnel (entre crochets et en première position) qui est le modèle
+colorimétrique pour la spécification des couleurs.
+
+\medskip
+\begin{itemize}
+\item La commande |\cellcolor| tient son nom de la commande |\cellcolor| de \pkg{colortbl}.
+
+Elle prend en arguments obligatoires une couleur et une liste de cases sous le format $i$-$j$ où $i$ est le
+numéro de ligne et $j$ le numéro de colonne.

+suivants fournissent la case en haut à gauche et la case en bas à droite du rectangle.

+\end{NiceTabular}
+\end{scope}
+
+
+
+\bigskip
+\item La commande |\rowcolor| doit son nom à la commande |\rowcolor| de \pkg{colortbl}. Son premier argument
+obligatoire est la couleur et le deuxième est une liste de numéros de rangées ou bien d'intervalles de rangées sous
+la forme $a$-$b$ (un intervalle de la forme $a$- représente toutes les rangées à partir de la rangée~$a$).

+\pkg{xcolor}\footnote{La commande |\rowcolors| de \pkg{xcolor} est disponible quand \pkg{xcolor} est chargé avec

+\section{La largeur des colonnes}
+\label{width}
+
+Dans les environnements avec un préambule explicite (comme |{NiceTabular}|, |{NiceArray}|, etc.), il est possible
+de fixer la largeur d'une colonne avec les lettres classiques |w| et |W| de l'extension \pkg{array}. Dans
+|{NiceTabular}|, les cases des colonnes de ce type sont composées en mode texte mais, dans |{NiceArray}|,
+|{pNiceArray}|, etc., elles sont composées en mode mathématique (alors que dans |{array}| de \pkg{array}, elles
+sont composées en mode texte).

+Dans les environnements de \pkg{nicematrix}, il est aussi possible de fixer la largeur \emph{minimale} de toutes

+dans les autres environnements) n'est pas supprimé (il est évidemment possible de le supprimer en mettant
+|\tabcolsep| ou |\arraycolsep| à~$0$ avant).
+
+\bigskip
+Il est possible de donner la valeur spéciale |auto| à l'option |columns-width|: toutes les colonnes du tableau
+auront alors une largeur égale à la largeur de la case la plus large du tableau.\footnote{Le résultat est atteint
+ dès la première compilation (mais Tikz écrivant des informations dans le fichier |.aux|, un message demandant une

+Les lignes pointillées ont été tracées avec les outils présentés p.~\pageref{Cdots}.
+
+
+\bigskip
+Il y a plusieurs remarques à formuler.
+%
+\begin{itemize}[beginpenalty=10000]
+\item Si on utilise un environnement avec préambule explicite (c'est-à-dire |{NiceArray}| ou l'une de ses
+variantes), on ne doit pas mettre dans ce préambule de spécification de colonne pour les éventuelles première et
+dernière colonne : ce sera automatiquement (et nécessairement) une colonne |R| pour la première colonne et une
+colonne |L| pour la dernière.
+
+\item On peut se demander comment \pkg{nicematrix} détermine le nombre de rangées et de colonnes nécessaires à la
+composition de la «dernière rangée» et de la «dernière colonne».
+
+\begin{itemize}
+\item Dans le cas d'un environnement avec préambule, comme |{NiceTabular}| ou |{pNiceArray}|, le nombre de colonnes
+se déduit évidemment du préambule.
+
+\item Dans le cas où l'option |light-syntax| (cf. p. \pageref{light-syntax}) est utilisée, \pkg{nicematrix} profite
+du fait que cette option nécessite de toutes manières le chargement complet du contenu de l'environnement (d'où
+l'impossibilité de mettre du verbatim dans ce cas-là) avant composition du tableau. L'analyse du contenu de
+l'environnement donne le nombre de rangées (mais pas le nombre de colonnes).
+
+\item Dans les autres cas, \pkg{nicematrix} détermine le nombre de rangées et de colonnes à la première compilation
+et l'écrit dans le fichier |.aux| pour pouvoir l'utiliser à la compilation suivante.
+
+\textsl{Néanmoins, il est possible de donner le numéro de la dernière rangée et le numéro de la dernière colonne en
+arguments des options |last-row| et |last-col|, ce qui permettra d'accélérer le processus complet de
+compilation.} C'est ce que nous ferons dans la suite.
+\end{itemize}
+
+\end{itemize}
+
+
+
+\bigskip
+On peut contrôler l'apparence de ces rangées et colonnes avec les options |code-for-first-row|,
+|code-for-last-row|, |code-for-first-col| et |code-for-last-col|. Ces options sont des listes de tokens qui seront
+insérées au début de chaque case de la rangée ou de la colonne considérée.

-L'extension \pkg{nicematrix} crée un nœud PGF-Tikz pour chaque case (non vide) du tableau considéré. Ces nœuds sont
-utilisés pour tracer les lignes en pointillés entre les cases du tableau. Toutefois, l'utilisateur peut aussi
-utiliser directement ces nœuds (s'il a chargé Tikz\footnote{On rappelle que depuis la version 3.13,
- \pkg{nicematrix} ne charge plus Tikz par défaut, mais seulement \textsc{pgf} (Tikz est une surcouche de

-sont accessibles à travers les noms «\textsl{nom}-$i$-$j$» où \textsl{nom} est le nom donné au tableau et $i$ et
-$j$ les numéros de rangée et de colonne de la case considérée.
+On a dit (cf. p. \pageref{hvlines}) que la clé |hvlines| trace tous les filets horizontaux et verticaux, exceptés

-l'espace des deux côtés du tableau et aussi de l'espace dans les «nœuds larges» de la première colonne et de la
-dernière colonne. Dans l'exemple suivant, nous avons utilisé les options |left-margin| et
-|right-margin|.\footnote{Les options |left-margin| et |right-margin| prennent des dimensions comme valeurs mais, si
- aucune valeur n'est donnée, c'est la valeur par défaut qui est utilisée et elle est égale à |\arraycolsep| (par

-Les environnements |{NiceArray}| et |{NiceTabular}| sont similaires aux environnements |{array}| et |{tabular}|.
-L'argument obligatoire est le préambule du tableau. Néanmoins, pour des raisons techniques, l'utilisateur doit
-utiliser les lettres |L|, |C| et |R|\footnote{Les types de colonnes |L|, |C| et |R| sont définis localement à

-\item Si on utilise un environnement avec préambule explicite (c'est-à-dire |{NiceArray}| ou l'une de ses

-colonne |L| pour la dernière.

-\begin{itemize}
-\item Dans le cas d'un environnement avec préambule, comme |{NiceTabular}| ou |{pNiceArray}|, le nombre de colonnes
-se déduit évidemment du préambule.
-
-\item Dans le cas où l'option |light-syntax| (cf. p. \pageref{light-syntax}) est utilisée, \pkg{nicematrix} profite
-du fait que cette option nécessite de toutes manières le chargement complet du contenu de l'environnement (d'où
-l'impossibilité de mettre du verbatim dans ce cas-là) avant composition du tableau. L'analyse du contenu de
-l'environnement donne le nombre de rangées (mais pas le nombre de colonnes).
-
-\item Dans les autres cas, \pkg{nicematrix} détermine le nombre de rangées et de colonnes à la première compilation
-et l'écrit dans le fichier |.aux| pour pouvoir l'utiliser à la compilation suivante.
-
-\textsl{Néanmoins, il est possible de donner le numéro de la dernière rangée et le numéro de la dernière colonne en
-arguments des options |last-row| et |last-col|, ce qui permettra d'accélérer le processus complet de
-compilation.} C'est ce que nous ferons dans la suite.

-\emph{Remarques}
-\begin{itemize}[beginpenalty=10000]
-\item Comme on peut le voir dans l'exemple précédent, un filet horizontal (tracé avec |\hline|) ne s'étend pas
-dans les colonnes extérieures et un filet vertical (spécifié par un caractère «\verb+|+» dans le préambule du
-tableau) ne s'étend pas dans les rangées extérieures.\footnote{Ce dernier point n'est pas valable si on a chargé,
- en plus de \pkg{nicematrix}, l'extension \pkg{arydshln}. Les extensions \pkg{nicematrix} et \pkg{arydshln} ne
- sont pas parfaitement compatibles car \pkg{arydshln} redéfinit beaucoup de structures internes à \pkg{array}. Par
-ailleurs, si on veut vraiment un filet qui s'étende dans la première et la dernière rangée, on peut utiliser
-|!{\vline}| dans le préambule à la place de \verb+|+.}
-
-Si on veut définir de nouveaux spécificateurs de colonnes pour des filets (par exemple plus épais), on aura
-peut-être intérêt à utiliser la commande |\OnlyMainNiceMatrix| décrite p.~\pageref{OnlyMainNiceMatrix}.
-\item Une spécification de couleur présente dans |code-for-first-row| s'applique à une ligne pointillée tracée
-dans cette «première rangée» (sauf si une valeur a été donnée à |xdots/color|). Idem pour les autres.
-\item Sans surprise, une éventuelle option |columns-width| (décrite p.~\pageref{width}) ne s'applique pas à la
-«première colonne» ni à la «dernière colonne».
-\item Pour des raisons techniques, il n'est pas possible d'utiliser l'option de la commande |\\| après la
-«première rangée» ou avant la «dernière rangée» (le placement des délimiteurs serait erroné).

-\section{Les matrices par blocs}
-
-\label{Block}
-
-Cette partie, qui introduit une commande |\Block|, n'a pas de rapport direct avec l'environnement
-|{NiceMatrixBlock}| présenté dans la section précédente.
-
-\smallskip
-Dans les environnements de \pkg{nicematrix}, on peut utiliser la commande |\Block| pour placer un élément au centre
-d'un rectangle de cases fusionnées.
-
-La commande |\Block| doit être utilisée dans la case supérieure gauche du bloc avec deux arguments. Le premier
-argument est la taille de ce bloc avec la syntaxe $i$-$j$ où $i$ est le nombre de rangées et $j$ le nombre de
-colonnes du bloc. Le deuxième argument, est, sans surprise, le contenu du bloc (en mode mathématique). Un nœud Tikz
-correspondant à l'ensemble des cases fusionnées est créé sous le nom «$i$-$j$-block» où \textsl{nom} est le
-nom donné au tableau. Si on a demandé la création des nœuds |medium|, alors un nœud de ce type est aussi créé pour
-ce bloc avec un nom suffixé par |-medium|.
-
-\medskip
-Dans les exemples qui suivent, on utilise la commande |\arrayrulecolor| de \pkg{colortbl}.
-
-\medskip
-\begin{BVerbatim}[baseline=c,boxwidth=10.6cm]

-
-\bigskip
-On peut souhaiter agrandir la taille du «$A$» placé dans le bloc de l'exemple précédent. Comme il est composé en
-mode mathématique, on ne peut pas directement utiliser une commande comme |\large|, |\Large| ou |\LARGE|. C'est
-pourquoi une option à mettre entre chevrons est proposée par |\Block| pour spécifier du code LaTeX qui sera inséré
-\emph{avant} le début du mode mathématique.

-Pour des raisons techniques, il n'est pas possible d'écrire |\Block{|$i$|-|$j$|}{<}|
-(mais on peut écrire |\Block{|$i$|-|$j$|}<>{<}| avec le résultat attendu).

-\section{Les couleurs des rangées et des colonnes}
-
-L'extension \pkg{colortbl} permet de colorier des cellules, des rangées ou des colonnes d'un tableau. Néanmoins,
-l'affichage du \textsc{pdf} résultant n'est pas toujours parfait, en particulier quand on utilise également des
-filets. Dans certains lecteurs de \textsc{pdf}, des filets verticaux semblent disparaître. De fines lignes
-blanches peuvent également apparaître.
-
-\medskip
-La version 4.0 de \pkg{nicematrix} propose des outils similaires qui ne présentent pas ces inconvénients. Elle
-propose une option |code-before| pour du code qui sera exécuté \emph{avant} le tracé du tableau. Dans ce
-|code-before|, de nouvelles commandes sont disponibles : |\cellcolor|, |\rectanglecolor|, |\rowcolor|,
-|\columncolor|, |\rowcolors| et |\chessboardcolors|.
-
-\medskip
-\begin{itemize}
-\item La commande |\cellcolor| tient son nom de la commande |\cellcolor| de \pkg{colortbl}.
-
-Elle prend en arguments une couleur et une liste de cellules sous le format $i$-$j$ où $i$ est le numéro de ligne
-et $j$ le numéro de colonne.

+\section{Utilisation de Tikz avec nicematrix}
+
+\label{name}
+
+\subsection{Les nœuds correspondant aux contenus des cases}
+
+L'extension \pkg{nicematrix} crée un nœud PGF-Tikz pour chaque case (non vide) du tableau considéré. Ces nœuds sont
+utilisés, entre autres, pour tracer les lignes en pointillés entre les cases du tableau.
+
+\smallskip
+Tous les nœuds du document doivent avoir des noms deux à deux distincts et le nom de ces nœuds doit donc faire
+intervenir le numéro de l'environnement courant. Les environnements créés par \pkg{nicematrix} sont en effet
+numérotés par un compteur global interne.
+
+\smallskip
+Si l'environnement concerné a le numéro $n$, alors le nœud de la rangée~$i$ et de la colonne~$j$ a pour nom
+|nm-|$n$|-|$i$|-|$j$.
+
+\smallskip
+La commande |\NiceMatrixLastEnv| donne le numéro du dernier de ces environnements (pour LaTeX, il s'agit d'une
+commande — complètement développable — et non d'un compteur).
+
+\smallskip
+Il est néanmoins recommandé de passer plutôt par la clé |name|. Celle-ci permet de donner un nom à l'environnement.
+Une fois l'environnement nommé, les nœuds sont accessibles à travers les noms «\textsl{nom}-$i$-$j$» où
+\textsl{nom} est le nom donné au tableau et $i$ et $j$ les numéros de rangée et de colonne de la case considérée.
+On peut les utiliser avec \textsc{pgf} mais l'utilisateur final préférera sans doute utiliser Tikz (qui est une
+sur-couche de \textsc{pgf}). Il faut néanmoins se souvenir que \pkg{nicematrix} ne charge pas Tikz par défault.
+
\bigskip
-Il y a néanmoins une différence entre l'utilisation de l'option |vlines| et du spécificateur «\verb+|+» dans le
-préambule de l'environnement : les filets tracés par |vlines| traversent les double-filets horizontaux tracés par
-|\hline\hline|.

\bigskip
-Dans le cas d'un environnement avec délimiteurs (par exemple |{pNiceArray}| ou |{pNiceMatrix}|), l'option |vlines| ne
-trace pas de filets verticaux au niveau des deux délimiteurs (bien entendu).
+Dans le |code-after|, et si Tikz est chargé, les choses sont plus simples. On peut (et on doit) désigner les nœuds
+sous la forme $i$-$j$ : il n'y a pas besoin de préciser l'environnement qui est évidemment l'environnement courant.

+anglais). Les premiers sont créés avec l'option |create-medium-nodes| et les seconds avec l'option

+% \section{The environments of this package}
+%
+% The package \pkg{nicematrix} defines the following new environments.
%
+% \medskip
+% \begin{ttfamily}
+% \setlength{\tabcolsep}{3mm}
+% \begin{tabular}{llll}
+% \{NiceTabular\} & \{NiceArray\} & \{NiceMatrix\} \\
+% & \{pNiceArray\} & \{pNiceMatrix\} \\
+% & \{bNiceArray\} & \{bNiceMatrix\} \\
+% & \{BNiceArray\} & \{BNiceMatrix\} \\
+% & \{vNiceArray\} & \{vNiceMatrix\} \\
+% & \{VNiceArray\} & \{VNiceMatrix\}
+% \end{tabular}
+% \end{ttfamily}
+%
+%
+%
+%
+% \medskip
+% The environments |{NiceArray}| and |{NiceTabular}| are similar to the
+% environments |{array}| and |{tabular}| of the package \pkg{array} (which is
+% loaded by \pkg{nicematrix} ).
+%
+% \medskip
+% However, there are some small differences:
+% \begin{itemize}
+% \item For technical reasons, in the preamble of these environments, the user
+% must use the letters |L|, |C| and~|R|\footnote{The column types |L|, |C| and
+% |R| are defined locally inside |{NiceTabular}| or |{NiceArray}| with
+% |\newcolumntype| of \pkg{array}. This definition overrides an eventual
+% previous definition.} instead of |l|, |c| and |r|, included in the commands
+% |\multicolumn| and in the types of columns defined by |\newcolumntype|.
+%
+% * In |{NiceArray}| (and its variants), the columns of type |w| (ex. :
+% |wc{1cm}|) are composed in math mode whereas, in |{array}| of \pkg{array},
+% they are composed in text mode.
+% \end{itemize}
+%
+% \medskip
+% The environments |{pNiceArray}|, |{bNiceArray}|, etc. have no equivalent in
+% \pkg{array}.
+%
+% \medskip
+% The environments |{NiceMatrix}|, |{pNiceMatrix}|, etc. are similar to the
+% corresponding environments of \pkg{amsmath} (which is loaded by
+% \pkg{nicematrix}): |{matrix}|, |{pmatrix}|, etc.
+%
+% \medskip
+% All the environments of the package \pkg{nicematrix} accept, between square
+% brackets, an optional list of \textsl{key=value} pairs. \textbf{There must be
+% no space before the opening bracket (|[|) of this list of options.}
+%
+% \section{The vertical space between the rows}
+%
+% It's well known that some rows of the arrays created by default with LaTeX
+% are, by default, too close to each other. Here is a classical example.
+%
+% \medskip
+% \begin{BVerbatim}[baseline=c,boxwidth=9cm]
+% $\begin{pmatrix}
+% \frac12 & -\frac12 \\
+% \frac13 & \frac14 \\
+% \end{pmatrix}$
+% \end{BVerbatim}
+% $\begin{pmatrix}
+% \frac12 & -\frac12 \\
+% \frac13 & \frac14 \\
+% \end{pmatrix}$
+%
% \bigskip
-% \textbf{An example for the continuous dotted lines}
+% Inspired by the package \pkg{cellspace} which deals with that problem, the
+% package \pkg{nicematrix} provides two keys |cell-space-top-limit| and
+% |cell-space-bottom-limit| similar to the parameters |\cellspacetoplimit| and
+% |\cellspacebottomlimit| of \pkg{cellspace}. The initial value of these
+% parameters is $0$~pt in order to have for the environments of \pkg{nicematrix}
+% the same behaviour as those of \pkg{array} and \pkg{amsmath}. However, a value
+% of $1$~pt would probably be a good choice and we suggest to set them with
+% |\NiceMatrixOptions|.
%

-% of \pkg{amsmath}.

+%
+%
+%
+%
+%
+% \bigskip
+% \section{The vertical position of the arrays}
+%
+% The package \pkg{nicematrix} provides a option |baseline| for the vertical
+% position of the arrays. This option takes as value an integer which is the
+% number of the row on which the array will be aligned.
+%
+% \medskip
+% \begin{BVerbatim}[baseline=c,boxwidth=9cm]
+% $A = \begin{pNiceMatrix}[~emphase#baseline=2@]
+% \frac{1}{\sqrt{1+p^2}} & p & 1-p \\
+% 1 & 1 & 1 \\
+% 1 & p & 1+p
+% \end{pNiceMatrix}$
+% \end{BVerbatim}
+% $A = \begin{pNiceMatrix}[baseline=2]
+% \frac{1}{\sqrt{1+p^2}} & p & 1-p \\
+% 1 & 1 & 1 \\
+% 1 & p & 1+p
+% \end{pNiceMatrix}$
+%
+%
+% \medskip
+% It's also possible to use the option |baseline| with one of the special values
+% |t|, |c| or |b|. These letters may also be used absolutely like the option of
+% the environments |{tabular}| and |{array}| of \pkg{array}. The initial value
+% of |baseline| is~|c|.
+%
+%
+% \medskip
+% In the following example, we use the option |t| (equivalent to |baseline=t|)
+% immediately after an |\item| of list. One should remark that the presence of a
+% |\hline| at the beginning of the array doesn't prevent the alignment of the
+% baseline with the baseline of the first row (with |{tabular}| or |{array}| of
+% \pkg{array}, one must use |\firsthline|\footnote{It's also possible to use
+% |\firsthline| in the environments of \pkg{nicematrix}.}).

+% \section{The blocks}
+% \label{Block}
+%
+% In the environments of \pkg{nicematrix}, it's possible to use the command
+% |\Block| in order to place an element in the center of a rectangle of merged
+% cells of the array. The command |\Block| don't create space by itself.
+%
+% The command |\Block| must be used in the upper leftmost cell of the array with
+% two arguments. The first argument is the size of the block with the syntax
+% $i$\verb|-|$j$ where $i$ is the number of rows of the block and $j$ its number
+% of columns. The second argument is the content of the block.
+%
+% In |{NiceTabular}| the content of the block is composed in text mode. In the
+% other environments, it is composed in math mode.

+% \section{The rules}
+%
+% The usual techniques for the rules may be used in the environments of
+% \pkg{nicematrix} (excepted |\vline|).
+%
+%
+% \subsection{The thickness and the color of the rules}
+%
+% The environments of \pkg{nicematrix} provide a key |rules/width| to set the
+% width (in fact the thickness) of the rules in the current environment. In
+% fact, this key merely sets the value of the length |\arrayrulewidth|.
+%

-% \vdots &\ddots &\ddots &\vdots \\
-% 0 &\cdots &0 &1
-% \end{pmatrix}$
+% It's well known that \pkg{colortbl} provides the command |\arrayrulecolor| in
+% order to specify the color of the rules.
%
+% \smallskip
+% With \pkg{nicematrix}, it's possible to specify the color of the rules even
+% when \pkg{colortbl} is not loaded. For sake of compatibility, the command is
+% also named |\arrayrulecolor|. The environments of \pkg{nicematrix} also
+% provide a key |rules/color| to fix the color of the rules in the current
+% environment.

+% \subsection{A remark about \textbackslash cline}
+%
+%\label{remark-cline}
+%
+% The horizontal and vertical rules drawn by |\hline| and the specifier
+% ``\verb+|+'' make the array larger or wider by a quantity equal to the width of the rule.

+% |\NiceMatrixOptions|.
%
+% \bigskip
+% \emph{Remark} : In the package \pkg{array} (on which the package
+% \pkg{nicematrix} relies), horizontal and vertical rules make the array larger
+% or wider by a quantity equal to the width of the rule\footnote{In fact, this
+% is true only for |\hline| and ``"|"'' but not for |\cline|.}. In
+% \pkg{nicematrix}, the dotted lines drawn by |\hdottedline| and ``|:|'' do
+% likewise.

+%
+%\section{The color of the rows and columns}
+%
+% With the classical package \pkg{colortbl}, it's possible to color the cells,
+% rows and columns of a tabular. However, the resulting \textsc{pdf} is not
+% always perfectly displayed by the \textsc{pdf} viewers, in particular in
+% conjonction with rules. With some \textsc{pdf} viewers, some vertical rules
+% seem to vanish. On the other side, some thin horizontal white lines may appear
+% in some circonstances.
+%
+%
+% \medskip
+% The package \pkg{nicematrix} provides similar tools which do not present these
+% drawbacks. It provides a key |code-before|\footnote{There is also a key
+% |code-after| : see p.~\pageref{code-after}.} for some code which will be
+% executed \emph{before} the drawing of the tabular. In this |code-before|, new
+% commands are available: |\cellcolor|, |\rectanglecolor|, |\rowcolor|,
+% |\columncolor|, |\rowcolors| and |\chessboardcolors|.
+% \label{code-before}
+%
+% \medskip
+% These commands are independent of \pkg{colortbl}.\footnote{Thus, it's possible
+% to coloror the rules, the cells, the rows, the columns, etc. without loading \pkg{colortbl}.}
+%
+% \medskip
+% All these commands accept an optional argument (between square brackets and
+% in first position) which is the color model for the specification of the colors.
+%
+% \medskip
+% \begin{itemize}
+% \item The command |\cellcolor| takes its name from the command |\cellcolor| of
+% \pkg{colortbl}.

+% We have several remarks to do.
+% \begin{itemize}
+% \item For the environments with an explicit preamble (i.e. |{NiceArray}| and
+% its variants), no letter must be given in that preamble for the potential
+% first column and the potential last column: they will automatically (and
+% necessarily) be of type |R| for the first column and |L| for the last one.
+% \item One may wonder how \pkg{nicematrix} determines the number of rows and
+% columns which are needed for the composition of the ``last row'' and ``last
+% column''.
+% \begin{itemize}
+% \item For the environments with explicit preamble, like |{NiceTabular}| and
+% |{pNiceArray}|, the number of columns can obviously be computed from the
+% preamble.
+%
+% \item When the option |light-syntax| (cf. p. \pageref{light-syntax}) is used,
+% \pkg{nicematrix} has, in any case, to load the whole body of the environment
+% (and that's why it's not possible to put verbatim material in the array with
+% the option |light-syntax|). The analysis of this whole body gives the number
+% of rows (but not the number of columns).
+%
+% \item In the other cases, \pkg{nicematrix} compute the number of rows and
+% columns during the first compilation and write the result in the |aux| file
+% for the next run.
+%
+% \textsl{However, it's possible to provide the number of the last row and the
+% number of the last column as values of the options |last-row| and |last-col|,
+% tending to an acceleration of the whole compilation of the document.} That's
+% what we will do throughout the rest of the document.
+% \end{itemize}
+% \end{itemize}
+%

+% It's possible to control the appearance of these rows and columns with options

+% \emph{Remarks}
+% \begin{itemize}[beginpenalty=10000]
+% \item As shown in the previous example, the horizontal and rules doesn't
+% extend in the exterior rows and columns.
+%
+% However, if one wishes to define new specifiers for columns in order to draw
+% vertical rules (for example thicker than the standard rules), he should
+% consider the command |\OnlyMainNiceMatrix| described on
+% page~\pageref{OnlyMainNiceMatrix}.
+%
+% \item A specification of color present in |code-for-first-row| also applies to
+% a dotted line draw in this exterior ``first row'' (excepted if a value has
+% been given to |xdots/color|). Idem for the other exterior rows and columns.
+%
+% \item Logically, the potential option |columns-width| (described
+% p.~\pageref{width}) doesn't apply to the ``first column'' and ``last column''.
+% \item For technical reasons, it's not possible to use the option of the
+% command |\\| after the ``first row'' or before the ``last row'' (the placement
+% of the delimiters would be wrong).

-%
-% \bigskip
-% The package \pkg{nicematrix} provides also the variants |{pNiceArray}|,
-%|{vNiceArray}|, |{VNiceArray}|, |{bNiceArray}| and |{BNiceArray}|.
%
-% \bigskip
-% Of course, one of the benefits of |{pNiceArray}| over |{pNiceMatrix}| is the
-% possibility of drawing vertical rules:
-%
-%\bigskip
-% \begin{BVerbatim}[baseline=c,boxwidth=10cm]
-% $\left[\begin{NiceArray}{CCCC|C}

-% \section{The vertical position of the arrays}
-%
-% The package \pkg{nicematrix} provides a option |baseline| for the vertical
-% position of the arrays. This option takes as value an integer which is the
-% number of the row on which the array will be aligned.
-%
-% \medskip
-% \begin{BVerbatim}[baseline=c,boxwidth=9cm]
-% $A = \begin{pNiceMatrix}[~emphase#baseline=2@]

-% 1 & p & 1+p
-% \end{pNiceMatrix}$
-% \end{BVerbatim}
-% $A = \begin{pNiceMatrix}[baseline=2]
-% \frac{1}{\sqrt{1+p^2}} & p & 1-p \\
-% 1 & 1 & 1 \\
-% 1 & p & 1+p
-% \end{pNiceMatrix}$
%
-%
-% \medskip
-% It's also possible to use the option |baseline| with one of the special values
-% |t|, |c| or |b|. These letters may also be used absolutely like the option of
-% the environment |{array}| of \pkg{array}. The initial value of |baseline| is~|c|.

-% In the following example, we use the option |t| (equivalent to |baseline=t|)
-% immediately after an |\item| of list. One should remark that the presence of
-% a |\hline| at the beginning of the array doesn't prevent the alignment of the
-% baseline with the baseline of the first row (with |{array}| of \pkg{array},

-%
-% \bigskip
-% We have several remarks to do.
-% \begin{itemize}
-% \item For the environments with an explicit preamble (i.e. |{NiceArray}| and
-% its variants), no letter must be given in that preamble for the potential
-% first column and the potential last column: they will automatically (and
-% necessarily) be of type |R| for the first column and |L| for the last one.
-% \item One may wonder how \pkg{nicematrix} determines the number of rows and
-% columns which are needed for the composition of the ``last row'' and ``last
-% column''.
-% \begin{itemize}
-% \item For the environments with explicit preamble, like |{NiceTabular}| and
-% |{pNiceArray}|, the number of columns can obviously be computed from the
-% preamble.
-%
-% \item When the option |light-syntax| (cf. p. \pageref{light-syntax}) is used,
-% \pkg{nicematrix} has, in any case, to load the whole body of the environment
-% (and that's why it's not possible to put verbatim material in the array with
-% the option |light-syntax|). The analysis of this whole body gives the number
-% of rows (but not the number of columns).
-%
-% \item In the other cases, \pkg{nicematrix} compute the number of rows and
-% columns during the first compilation and write the result in the |aux| file
-% for the next run.
-%
-% \textsl{However, it's possible to provide the number of the last row and the
-% number of the last column as values of the options |last-row| and |last-col|,
-% tending to an acceleration of the whole compilation of the document.} That's
-% what we will do throughout the rest of the document.
-% \end{itemize}
-% \end{itemize}
-%
-% \bigskip
-% It's possible to control the appearance of these rows and columns with options
-% |code-for-first-row|, |code-for-last-row|, |code-for-first-col| and

-% \emph{Remarks}
-% \begin{itemize}[beginpenalty=10000]
-% \item As shown in the previous example, an horizontal rule (drawn by |\hline|)
-% doesn't extend in the exterior columns and a vertical rule (specified by a
-% ``\verb+|+'' in the preamble of the array) doesn't extend in the exterior
-% rows.\footnote{The latter is not true when the package \pkg{arydshln} is
-% loaded besides \pkg{nicematrix}. In fact, \pkg{nicematrix} and \pkg{arydhsln}
-% are not totally compatible because \pkg{arydshln} redefines many internals of
-% \pkg{array}. On another hand, if one really wants a vertical rule running in
-% the first and in the last row, he should use |!{\vline}| instead of \verb+|+
-% in the preamble of the array.}
-%
-% If one wishes to define new specifiers for columns in order to draw vertical
-% rules (for example thicker than the standard rules), he should consider the
-% command |\OnlyMainNiceMatrix| described on page~\pageref{OnlyMainNiceMatrix}.
-%
-% \item A specification of color present in |code-for-first-row| also applies to
-% a dotted line draw in this exterior ``first row'' (excepted if a value has
-% been given to |xdots/color|). Idem for the other exterior rows and columns.
-%
-% \item Logically, the potential option |columns-width| (described
-% p.~\pageref{width}) doesn't apply to the ``first column'' and ``last column''.
-% \item For technical reasons, it's not possible to use the option of the
-% command |\\| after the ``first row'' or before the ``last row'' (the placement
-% of the delimiters would be wrong).
-% \end{itemize}
-%
-%
-%
-%
-%
-% \section{The dotted lines to separate rows or columns}
-%
-%
-% In the environments of the package \pkg{nicematrix}, it's possible to use

-% \label{Block}
-%
-% This section has no direct link with the previous one where an environment
-% |{NiceMatrixBlock}| was introduced.
-%
-% In the environments of \pkg{nicematrix}, it's possible to use the command
-% |\Block| in order to place an element in the center of a rectangle of merged
-% cells of the array.
-%
-% The command |\Block| must be used in the upper leftmost cell of the array with
-% two arguments. The first argument is the size of the block with the syntax
-% $i$\verb|-|$j$ where $i$ is the number of rows of the block and $j$ its number
-% of columns. The second argument is the content of the block (composed in math
-% mode). A Tikz node corresponding to the merged cells is created with the name
-% ``$i$-$j$-block''. If the user has required the creation of the ``medium
-% nodes'', a node of this type is also created with a name suffixed by
-% |-medium|.
-%
-% \medskip
-% In the following examples, we use the command |\arrayrulecolor| of
-% \pkg{colortbl}.

-% \section{The color of the rows and columns}
-%
-% With the classical package \pkg{colortbl}, it's possible to color the cells,
-% rows and columns of a tabular. However, the resulting \textsc{pdf} is not
-% always perfectly displayed by the \textsc{pdf} viewers, in particular in
-% conjonction with rules. With some \textsc{pdf} viewers, some vertical rules
-% seem to vanish. On the other side, some thin horizontal white lines may appear
-% in some circonstances.
-%
-%
-% \medskip
-% The version 4.0 of \pkg{nicematrix} provide similar tools which do not
-% present these drawbacks. This version provides a key |code-before| for some
-% code which will be executed \emph{before} the drawing of the tabular. In this
-% |code-before|, new commands are available: |\cellcolor|, |\rectanglecolor|,
-% |\rowcolor|, |\columncolor|, |\rowcolors| and |\chessboardcolors|.

+% \section{Utilisation of Tikz with nicematrix}
%
+% \label{name}
+% \subsection{The nodes corresponding to the contents of the cells}
+%
+% The package \pkg{nicematrix} creates a PGF/Tikz node for each (non-empty) cell
+% of the considered array. These nodes are used to draw the dotted lines between
+% the cells of the matrix (inter alia).
+%
+% \smallskip
+% The nodes of a document must have distinct names. That's why the names of the
+% nodes created by \pkg{nicematrix} contains the number of the current
+% environment. Indeed, the environments of \pkg{nicematrix} are numbered by a
+% internal global counter.
+%
+% \smallskip
+% In the environment with the number $n$, the node of the row $i$ and
+% column~$j$ has for name |nm-|$n$|-|$i$|-|$j$.
+%
+% \smallskip
+% The command |\NiceMatrixLastEnv| provides the number of the last environment
+% of \pkg{nicematrix} (for LaTeX, it's a ``fully expandable'' command and not a
+% counter).
+%
+% \smallskip
+% However, it's advisable to use instead the key |name|. This key gives a name
+% to the current environment. When the environment has a name, the nodes are
+% accessible with the name ``\textsl{name}-$i$-$j$'' where \textsl{name} is the
+% name given to the array and $i$ and $j$ the numbers of row and column. It's
+% possible to use these nodes with \textsc{pgf} but the final user will
+% probably prefer to use Tikz (which is a convenient layer upon \textsc{pgf}).
+% However, one should remind that \pkg{nicematrix} doesn't load Tikz by default.

+% \subsection{The ``medium nodes'' and the ``large nodes''}
+%
+% In fact, the package \pkg{nicematrix} can create ``extra nodes'': the ``medium
+% nodes'' and the ``large nodes''. The first ones
+% are created with the option |create-medium-nodes| and the second ones with the
+% option |create-large-nodes|.\footnote{There is also an option

+% we have used the options |left-margin| and |right-margin|.\footnote{The
