With the following, I can get a table in "two columns" - it is possible to make it three?
It is possible by splitting the whole table by human hand, but there should be some automatic solutions.
\documentclass[twocolumn]{article}
\usepackage{xtab,booktabs}
\usepackage[textheight=10cm]{geometry} %% just for this example.
\begin{document}
\topcaption{This is top caption}
\bottomcaption{This is bottom caption}
\tablecaption{this is table caption}
\tablefirsthead{\toprule First&\multicolumn{1}{c}{Name} \ \midrule}
%
\tablehead{%
\multicolumn{2}{c}%
{{\bfseries Continued from previous column}} \
\toprule
First&\multicolumn{1}{c}{Name}\ \midrule}
%
\tabletail{%
\midrule \multicolumn{2}{r}{{Continued on next column}} \ \midrule}
\tablelasttail{%
\\midrule
\multicolumn{2}{r}{{Concluded}} \ \bottomrule}
