Well here it is! (First draft, anyway.) Rules of the game: \begin{itemize} \item Put the \texttt{longtable} environment using \texttt{tabularx} style \texttt{X} column specifiers in a file \emph{file} on its own. (You can use the \texttt{filecontents} environment to include it back into the main document file, if you wish.) \item If you want to input the file at some point, using the \texttt{X} columns to force the table width to be \emph{width} wide, go \verb|\LTXtable{|\emph{width}\verb|}{|\emph{file}\verb|}|. \item \verb|\multicolumn|: If you read the \texttt{tabularx} and \texttt{longtable} docs you will find that both packages have a lot of fun with this command. In order to keep my sanity, for this merger I disable \texttt{longtable}'s version of \verb|\multicolumn|. This means that the column widths calculated are not always the same (not as good as) the widths that would be calculated by an equivalent \texttt{tabularx} environment. Perhaps one day I will do something about this. Perhaps. \end{itemize} \clearpage \centering A 300pt rule, just so can see the required width. \mbox{\vrule width 300pt height 1pt} First a tabularx \begingroup \renewenvironment{longtable}{\noindent\tabularx{300pt}}{\endtabularx} \def\endhead{\\}\def\endfoot{\rlap{ !!!}\\} \input{ltx1} \endgroup Then a longtable \LTXtable{300pt}{ltx1} \end{document} 1995/11/07 v0.1 first release 1995/12/11 v0.2 (Petr Sojka) Typos fixed so the package works!
