Multiline listing within multicolumn row

Question

I have a problem putting a listing (using lstlisting package) within a table. The problem is that I want to put a multiline listing in a row taking 2 columns.

The following minimal example shows what I want to achieve. However, multicolumn wraps the listing on a single line.

\documentclass{article}
\usepackage{listings}
\lstset{basicstyle=\ttfamily}
\begin{document}

\begin{table}[h]
\begin{center}
\begin{tabular}{ |l|l| }
\hline
\multicolumn{2}{|l|}{
  \begin{lstlisting}^^J
    1st line
    2nd line
  ^^J\end{lstlisting}
} \\ \hline
some text & some text \\ \hline
\end{tabular}
\end{center}
\end{table}

\end{document}

I've tried to wrap the listing in a vbox or minipage, but that didn't help.

Any alternatives to multicolumn, or other ways to get a multiline listing in a table like this?

Answer 1

an l column is like \mbox and is for single line material normally you would just need to change l to p{5cm} in your \multicolumn, however listings like most verbatim things can not be in the argument of another command so a sleight of hand is needed to avoid putting it in the argument of \multicolumn.

I also change begin{center} to \centering to avoid extra white space, and changed [h] as [h] means "please take all floats to end of document, which isn't normally the desired behaviour.

\documentclass{article}
\usepackage{listings}
\lstset{basicstyle=\ttfamily}
\begin{document}

\begin{table}[htbp]
\centering
\begin{tabular}{ |l|l| }
\hline
\multicolumn{2}{|}{}
  \begin{minipage}{5cm}
  \begin{lstlisting}
    1st line
    2nd line
  \end{lstlisting}
  \end{minipage}\hfill\vline\kern-\arrayrulewidth
 \\ \hline
some text & some text \\ \hline
\end{tabular}

\end{table}

\end{document}

Answer 2

\documentclass{article}
\usepackage{listings,array,varwidth}
\lstset{basicstyle=\ttfamily}
\begin{document}

\begin{table}[htbp]
\centering
\begin{tabular}{ |l|l| } \hline
\multicolumn{2}{|}{}
  \varwidth{\linewidth}
  \begin{lstlisting}
    1st line
    2nd line
  \end{lstlisting}
  \endvarwidth\hfill\vline
 \\ \hline
some text & some text \\ \hline
\end{tabular}

\end{table}

\end{document}
