The following code snippet does not work:

\documentclass{minimal}
\usepackage{longtable}
\usepackage{ifthen}
\newcounter{xyz}
\setcounter{xyz}{0}

\begin{document}

\begin{longtable}{|*2{c|}}
\hline
\whiledo{\value{xyz}<10}%
{%
\thexyz & something\stepcounter{xyz} \\\hline%
}%
\end{longtable}
\end{document}

  • thanks for the solution. This solution is also informative that lets me know the plain tex.

Try this:

\documentclass{article}
\usepackage{longtable}
\usepackage{ifthen, xspace}
\newcounter{xyz}
\setcounter{xyz}{0}

\begin{document}
\def\and{&\xspace}
\begin{longtable}{|*2{c|}}
\hline
\whiledo{\value{xyz}<10}%
{%
\thexyz \and something\stepcounter{xyz} \\\hline%
}%
\end{longtable}
\end{document}

Edit Changed from minimal class to article (see comments).

    I don't think that's the right way to do things. I'm not sure exactly what's going on here, but the rules don't appear so something fishy is going on.

  • thanks for answering. I got a result without horizontal and vertical tabular rules after compiling your code.

    @xport: changing the class to article solves the problem (although I don't know why).

    @Forgiver Yes, it was due to the OP having used the minimal class. There was a follow up question by Bruno, will find it out a bit later and post the link.
