%% This is file ltablex.sty (v1.1, August 2014)
%%
%% Patches to solves the caption issue:
%% Rolf Niepraschk (Rolf.Niepraschk@gmx.de), 2014/08/13
%%
%%
%% (C) Author: Anil K. Goel (akgoel@uwaterloo.ca)
%%
%% This program can be redistributed and/or modified under the terms
%% of the LaTeX Project Public License Distributed from CTAN archives
%% in directory macros/latex/base/lppl.txt.
%%
%% The file modifies the tabularx environment to
%% combine the features of the tabularx package
%% (auto-sized columns in a fixed width table)
%% with those of the longtable package
%% (multi-page tables).
%%
%% The tables are typeset using the tabularx environment
%% and the longtable environment is used internally to
%% handle multi-page tables. The \setlongtables feature
%% is used, and, therefore, the document should be
%% run through latex twice.
%%
%% Another feature that has been added is to treat the X
%% columns like 'l' columns if the table contents would allow
%% that to happen without exceeding the specified width of
%% the table. In other words, the specified width is
%% treated as the maximum allowed and not the exact width
%% of the table. This feature is the default but can be
%% disabled (or enabled) with \keepXColumns (or \convertXColumns).
%%
%% Caveats:
%% . The document needs to be latexed a couple times in general.
%% . In general, it is necessary to remove the .aux file before
%% the first latex run on the document.
%% . The table should not be larger than TeX's memory capacity
%%
%%
%% Here is a a simple usage example:
%%
%%
%% \documentclass{article}
%%
%% \usepackage{ltablex}
%%
%% \textheight=4in
%%
%% \begin{document}
%%
%% % we want a table that is \textwidth long, has 4 columns, columns 1
%% % and 3 are auto sized with the 3rd columns being 3 times wider than
%% % the first column.
%% %
%%
%%
%% \begin{tabularx}{\linewidth}%
%% {|>{\setlength{\hsize}{.5\hsize}\raggedright\arraybackslash}X| % col 1; auto-sized ragged right
%% c| % col 2; default centered
%% >{\setlength{\hsize}{1.5\hsize}\raggedleft\arraybackslash}X|% col 3; auto-sized ragged left
%% l|} % col 4; default left-justified
%%
