I knew I should've tested that code.

\documentclass{article}
\usepackage{xparse}
\usepackage{array}
\ExplSyntaxOn
\DeclareDocumentCommand{\maketable}{mm}
 {
   \exp_args:Nnx \begin{tabular}{c*{\clist_length:n{#2}}c}
   \clist_map_inline:nn {#2} { & \typeset_two:n {##1} }
   \clist_map_inline:nn {#1}
     {
        \\
        \typeset_one:n {##1}
        \clist_map_inline:nn {#2}
           { & \typeset_both:nn {##1} {####1} }
     }
   \end{tabular}
 }
\cs_new_protected:Npn \typeset_one:n #1 { [#1] }
\cs_new_protected:Npn \typeset_two:n #1 { (#1) }
\cs_new_protected:Npn \typeset_both:nn #1#2 {#1#2}
\ExplSyntaxOff
\begin{document}
\maketable{0,1}{a,b,c}
\end{document}

works. The previous code was mostly missing \usepackage{array} for the
"*{<number>}c" construction, and had a bunch of other bugs. To
customize that, change the definition of the three functions
\typeset_one:n, \typeset_two:n and \typeset_both:n.

Building diacritics from the base accent and the character seems a bit
tougher than I thought. Others on this thread will know how to do
that.

Cheers,
Bruno
