Multi column table in latex

You want a table the spans across pages and raps in 2 columns. You need supertabular and to stick everything in a \twocolumn. Do it:

\pagebreak
\twocolumn
\begin{supertabular}{ |l|c|l| }
\hline
stuff1 & stuff2 & stuff3 \\
1 & 2 & 3 \\
1 & 2 & 3 \\
1 & 2 & 3 \\
1 & 2 & 3 \\
1 & 2 & 3 \\
1 & 2 & 3 \\
1 & 2 & 3 \\
1 & 2 & 3 \\
1 & 2 & 3 \\
1 & 2 & 3 \\
1 & 2 & 3 \\
1 & 2 & 3 \\
\hline
\end{supertabular}
\onecolumn
\pagebreak
