I have a long table in my (two column) Latex document. For that reason, I am using:

\usepackage{longtable}

so that I can split the table over two pages. This seemed to work, but it seems that the table is trying to fit into 1 column instead of spanning the two. I didn't have this problem when I used tabular.

I include a MWE below, but I have truncated the table to only have a few rows:

Any ideas would be great.

MWE:

\documentclass{emulateapj}

\newcommand{\vdag}{(v)^\dagger}

\usepackage{tabularx,colortbl}

\usepackage{stackengine}
\setstackEOL{\cr} %EOL is abbreviation for ``end of line.''                                                        
\usepackage[table]{xcolor}

\begin{document}
\begin{longtable}{ccccccccccccc}

  • Sorry about that. Hopefully it should be working now. Apr 26, 2017 at 21:16
  • just put \onecolumn before the table and \twocolumn after it Apr 26, 2017 at 23:18
  • I just tried that with my MWE and I just got the error message that ended: ! Undefined control sequence. l.19 \onecolumn Apr 27, 2017 at 0:14

Use supertabular instead:

\documentclass[twocolumn,landscape]{scrartcl}
\usepackage{geometry}
\usepackage{supertabular}                                             
\usepackage[table]{xcolor} 
\begin{document}

\bottomcaption{Caption.\label{var_table}}
\tablefirsthead{%
    \hline
    \hline
        Name && col2 && col3 && col4 && col5 && col6 \\\hline}
\begin{supertabular}{ccccccccccccc}
    \rowcolor{gray!50}

  • Thank you. But I want my table to be span both of the columns. I just want the table to be one column in the middle of the page. It did this okay with "tabular", but then it split into two columns when I switched to "longtable". Am I able to have the table span the whole page in "supertabular"? Apr 26, 2017 at 23:14

So apparently I just needed to use

\begin{longtable*}

and

\end{longtable*}

instead of

\begin{longtable}

and

\end{longtable}

Now it works!
