[Tex/LaTex] How to typeset LaTeX code inside a Table environment

best practicescodeverbatim

I wanted to typeset LaTeX code directly into my document, but without it doing something, i.e., I just want to show my code in the output.

Now, I know there is the verbatim environment for code, as well as the listings package for this, but I am wondering what the best method for typesetting LaTeX code directly is (if there is one), without needing any extra packages.

A few days ago I tried to do it inside a table, and I came up with this question: Print small TeX code verbatim and render it

but still, they managed to do something different, as it automatically included the showcase.

I just want to be able to write a LaTeX code snippet easily and inside a normal environment, say, tables. What is the best way to do it?

The syntax for \verb is

\verb<char><text><char>

where <char> should be a (non special) character not found in <text>. Most often | or + are used for <char>.

A verbatim environment doesn't make sense in a table cell belonging to a column declared as l, c or r, just like a quote environment doesn't make sense in the argument to \mbox.

If you have multiline verbatim to be used in a cell column, you need to use a p column, but with some adjustments.

Notes:

It is better to import the VBA source code from within your TeX input file using \lstinputlisting[<options>]{filename.vb}. This way will make your TeX input file clean.
Try my style B by changing style=A to style=B.

[Tex/LaTex] Environment code undefined

You don't have an environment called code. If you are trying to print code, you might be interested in the verbatim environment, or other pretty-printing environments/packages. See Print programs with its proper syntax.

Wrapping your code snippet into a minimal compiling document using verbatim, it produces the following output:

enter image description here

\documentclass{article}
\begin{document}
\begin{minipage}{7cm}%
\begin{verbatim}
module Dir where

import TeX
import Data.List
\end{verbatim}
\end{minipage}\hfill
\begin{minipage}{7cm}%
\begin{verbatim}
module DirV where

import TeX
import Data.List
\end{verbatim}
\end{minipage}
\end{document}
