# How to set the space between columns provided by the multcol package? [duplicate]

According to the multcol package's user manual (2017/4/15, p. 3)

The space between columns is controlled by the length parameter \columnsep.

Unfortunately, there is no example showing how to use this parameter.

How can the space between columns be set?

Attempted solution

\documentclass{article}
\usepackage{multicol}
\usepackage{lipsum}
\begin{document}
\begin{multicols}{2}
\setlength{\columnsep}{0cm}
\lipsum[1-4]
\end{multicols}
\end{document}


but the resulting pdf file is the same whether or not the line \setlength{\columnsep}{0cm} is commented out, namely

• \setlength{\columnsep}{1cm}? – Troy Jun 11 '17 at 8:46
• @Troy: \setlength{\columnsep}{1cm} has no effect whatsoever. – Evan Aad Jun 11 '17 at 8:55
• @EvanAad place the \setlength{...} before beginning the multicols envt. – Troy Jun 11 '17 at 9:01
