How to put Verbatim inside \multicolumn in tabular?

Question

I need to put Verbatim text in tabular cell, which works fine, except when I want to extend the cell to all the columns, then I get an error

  File ended while scanning use of \FancyVerbGetLine.

Here is MWE which works, then will show the one that gives the error

\documentclass{article}
\usepackage{fancyvrb}
\begin{document}

\begin{tabular}{|p{2in}|p{2in}|}       \hline
text & text \\\hline
%
\begin{Verbatim}
verbatim text here
\end{Verbatim}
&
\\\hline
%
text & text    \\\hline
\end{tabular}
\end{document}

But the actual cell I have is long and has Verbatim in it and I needed to extend it over all columns.

\documentclass{article}
\usepackage{fancyvrb}
\begin{document}

\begin{tabular}{|p{2in}|p{2in}|}       \hline
text & text \\\hline
%
\multicolumn{2}{|p{4in}|}
{
\begin{Verbatim}
  verbatim text here
\end{Verbatim}
} 
\\\hline
%
text & text    \\\hline
\end{tabular}
\end{document}

Now

.
\FV@Error ... {FancyVerb Error:

l.13 }

This sounds like another one of those environment not allowed inside another environment type issues, which I need help resolving since I do not know how to fix this.

Answer 1

You cannot include verbatim environment inside table, because the macro you are using for tables reads the data as parameter text. It means that the text is tokenized already and cannot be re-tokenized by verbatim environment.

One solution is usage of \halign primitive directly, but this is not, what you probably want. Second solution is to prepare the box with verbatim environment before usage of the tabular environment:

\documentclass{article}
\usepackage{fancyvrb}
\newbox\verbbox
\begin{document}

\setbox\verbbox=\vbox{\hsize=4in
\begin{Verbatim}
  verbatim text here $ \ & etc.
\end{Verbatim}
}

\begin{tabular}{|p{2in}|p{2in}|}       \hline
text & text \\\hline
%
\multicolumn{2}{|c|}
{
\box\verbbox
}
\\\hline
%
text & text    \\\hline
\end{tabular}
\end{document}
