# Using supertabular, how do I create a single column table in a 2 column document?

My document has 2 columns. I am trying to create a table that has a single column (i.e. a single entry in each line) but can split across both columns of the document, and even go to the next page. I am using supertabular, which I only half understand, and at this point, I have written this

\documentclass[12pt,aps,prb,twocolumn, nofootinbib]{report}
\usepackage[utf8]{inputenc}
\usepackage{supertabular,booktabs}
\usepackage{array}
\begin{document}
\begin{center}
\tablefirsthead{%
\hline
\multicolumn{1}{|c|}{\tbsp Number}
\hline}
%

\tablehead{%
\hline
\multicolumn{1}{|c|}{\tbsp Number}
\hline}
%
\tabletail{%
\midrule \multicolumn{1}{r}{{Continued on next column}} \\ \midrule}

\begin{supertabular}{l}
\hline
42\\ \hline
347\\ \hline
\end {supertabular}
\end{center}
\end{document}

which does not work, instead it gives me a lot of errors and it is unable to compile. What am I doing wrong, and is there a better/simpler way of doing this?

• What do you mean by "it doesn't work"? Also please extend your snippet to a complete document that can be compiled and tested directly. – Ulrike Fischer Jul 19 '19 at 9:16
• Welcome to TeX.SX! Please make your code compilable (if possible), or at least complete it with \documentclass{...}, the required \usepackage's, \begin{document}, and \end{document}. That may seem tedious to you, but think of the extra work it represents for TeX.SX users willing to give you a hand. Help them help you: remove that one hurdle between you and a solution to your problem. – Alessandro Cuttin Jul 19 '19 at 9:33

You are missing a few \\ - \hline should come always after a it. And \tbsp is not defined, so I removed it. With this changes your example compiles fine:

\documentclass[12pt,aps,prb,twocolumn, nofootinbib]{report}
\usepackage[utf8]{inputenc}
\usepackage{supertabular,booktabs}
\usepackage{array}
\begin{document}
\begin{center}
\tablefirsthead{%
\hline
\multicolumn{1}{|c|}{ Number}
\\\hline}
%%
%
\tablehead{%
\hline
\multicolumn{1}{|c|}{ Number}
\\\hline}
%%
\tabletail{%
\midrule \multicolumn{1}{r}{{Continued on next column}} \\ \midrule}

\begin{supertabular}{l}
\hline
42\\ \hline
347\\ \hline
\end {supertabular}
\end{center}
\end{document}

If your table will fit in single page, then you can try with:

\begin{table*}
\caption{...}
\begin{tabular}{..}
...
...
\end{tabular}
\end{table*}

No need to go with supertabular or longtable, which are mainly used for tables which exceeds more than a page...
