I am writing a Paper in Latex for with the De Gruyter open style. In general I have a two-column Layout but i need to exclude two big tables that should be horizontal on full pages because they are quite big. As you can see in the code sample I used the landscape and the longtable environments for that.

\begin{longtable}{p{0.5cm} | p{4cm} | p{7cm} | p{9cm}}
& X & Y & Z \\
\hline \hline
1 & AAA \newline BBB & Lorem Ipsum & 
    \item q
    \item r
    \item s
\end{itemize} \\
& X & Y & Z \\
\hline \hline
2 & DDD \newline EEE & Lorem Ipsum & 
    \item t
    \item u
    \item v
\end{itemize} \\




I get a decent output but I also get many errors. They are all of the same kind:

! Undefined control sequence.
<template> ...vtop \@startpbox {0.5cm}\@tablefont 
l.74 &
       X & Y & Z \\
The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.

Maybe you have an idea where to look for a solution or why those errors occur. I do not really have a clue at all. Since the .sty-file from De gruyter is quite large I do not include it here but if you think it is needed for solving the error it can be found here: http://www.degruyter.com/dg/page/59/production

I hope that you can help me.

Thanks in advance.

    Welcome to the site! Generally it's better to create complete documents demonstrating the problem, rather than snippets. Your error can for example be reproduced by a quite small document: documentclass{article} \usepackage[small]{dgruyter} \usepackage{longtable} \begin{document} \begin{longtable}{p{3cm}} a \end{longtable} \end{document}. Without the dgruyter package the document works fine, so it seems to be conflicting with longtable. Aug 26, 2015 at 14:48
  • Thank you for the answer. Do you have an idea how to solve this conflict? I am quite new to Latex and I do not even know where to start.

  • If I knew I would have said so, I just wanted to highlight that small complete examples are better than isolated snippets for demonstrating a problem. If my example reproduces the problem on your system as well, you could always edit your question to include it in addition to/instead of your snippet. Aug 26, 2015 at 18:41

You could just put


in the preamble to give this a default definition, however the class obviously intends you to use supertabular rather than longtable for long tables as that package is loaded already by the class file and supertabular as well as a standard tabular are patched by the class with code to support \@tablefont.

Unrelated but it's depressing to see the file is still distributed with


at the top of the file, which pretty much breaks all LaTeX dimension calculations.
