I've this very long table to put in the appendix of a 2 column, IEEEtran conference paper. I'm trying to use longtable, but apparently longtable has to be used in one column mode only.

Is there a way to switch to one column for the appendix only?

Thanks

\documentclass[10pt,letterpaper,conference]{IEEEtran}
\usepackage[cmex10]{amsmath}
\interdisplaylinepenalty=2500
\usepackage{graphicx}
\usepackage{longtable}

\begin{document}
blah...

\appendix

\begin{longtable}[t]
blah...
\end{longtable}

\end{document
10

You can interrupt two column mode by issuing the command \onecolumn; however, you might want to issue \clearpage prior or \newpage before you do so. Then when you are done with the long table you can re-instate two column mode with \twocolumn.

If this doesn't work in IEEEtran, you could probably do \usepackage{supertabular} and use the floating supertabular environment to break up the two column. The supertabular documentation says the * variant works like tabular*.
