[texhax] Hacking array.sty

[Vafa Khalighi]

Hello

I eventually came up with a hack for array.sty that make it work in RTL,
this is what I have done:

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\documentclass{article}
\usepackage{array}
\makeatletter
\TeXXeTstate=1
\def\@tabular{%
  \leavevmode
  \hbox \bgroup \beginR $\col at sep\tabcolsep \let\d at llarbegin\begingroup
                                    \let\d at llarend\endgroup
  \@tabarray}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\def\endarray{\crcr\egroup\egroup\endR\egroup \egroup \gdef\@preamble{}}
\def\endtabular{\endarray $\endR\egroup}
\expandafter\let\csname endtabular*\endcsname=\endtabular
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\def\@array[#1]#2{\setbox\@arstrutbox=\hbox{\vrule
             height\arraystretch \ht\strutbox
             depth\arraystretch \dp\strutbox
             width\z@}\@mkpream{#2}\xdef\@preamble{\noexpand \halign
\@halignto
                  \bgroup \tabskip\z@ \@arstrut \@preamble
                          \tabskip\z@ \cr}
\if #1t\vtop \else \if#1b\vbox \else \vcenter \fi \fi
\bgroup \let\par\relax
\let\@sharp##\let\protect\relax \lineskip\z@\baselineskip\z@\m at th
\hbox\bgroup\beginR\vbox\bgroup
\@preamble}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\makeatother
\begin{document}
\begin{tabular}{|l|l|}\hline
vafa&khalighi\\ \hline
\end{tabular}
\end{document}




But unfortunately when compiling the document, I get the following error:
