[XeTeX] Automate table creation

As Tobias mentions, use a package for loops. I think the code below
should work, but I don't know how to build diacritics on a letter:
isn't the point of combining marks that just putting the two
characters next to each other should do the trick? I didn't test.

    \use:x { \noexpand\begin{tabular}{*{\clist_length:n{#2}}} }
    \clist_map_inline:nn {#2} { & ##1 }
    \clist_map_inline:nn {#1}
         \clist_map_inline:nn {#2}
            { & \build_diacritic:nn {##1} {####1} }
\cs_new_protected:Npn \build_diacritic:nn #1#2 {#1#2} % dunno?
