Hi Michal;

I ended up removing this package from building pdf also.

I found it conflicts with lualatex/pdflatex also when loading longtable package:

---------------------
\documentclass[12pt]{report}
\usepackage{arydshln}
\usepackage{longtable}
\begin{document}
\begin{longtable}{|l|l|l|}\hline
text
& text 1
& text 2
\\\hline
\end{longtable}
\end{document}
----------------------

and now

(base) >lualatex foo4.tex
This is LuaHBTeX, Version 1.12.0 (TeX Live 2020)
  restricted system commands enabled.
(./foo4.tex

                                                                                \@elt {#3}{\number \@tempcnta }{\number \@tempcntb }{\adl at dashcolor }{\adl at gapcolor }}

    ext
?

=============

So it is of no use for me, since I use longtable everywhere.

I am trying to find alternative package, which makes dashed lines in
array like this does, that would work in tex4ht and pdf mode,
and causes no problems.
