column width for text without space

Question

how is it possible to control the column width in a table having a very long text without space.

\begin{table}
  \begin{tabular}{l p{2cm}}
    datapath & /home/username/path/to/directory/very/long
 \end{tabular}
\end{table}

p{2cm} only works if the second column element was something like /home/ username/ path/ to/ directory /very /long. Am I doing something wrong here ?

Answer 1

Borrow the idea from David but use \path instead (since it is a path)

\documentclass{article}
\usepackage{url}
\begin{document}
  \begin{table}
  \begin{tabular}{l p{2cm}}
    datapath & \path{/home/username/path/to/directory/very/long}
 \end{tabular}
\end{table}
\end{document}
