I’m having trouble combining the dgruyter and caption packages.

The following code does not run with the dgruyter package (see my comments).

I appreciate your help.

The example can be reduced to

documentclass[ngerman]{article}

usepackage[small]{dgruyter} % ONLY WORKS IF I COMMENT THIS

usepackage{longtable}

begin{document}

begin{longtable}{|c|c|c|c|}

caption{A simple longtable example} label{tab:stat} \

A & B & C & D \

end{longtable}

end{document}

which leads to the error message

! Undefined control sequence.

@preamble ...skip 1spd@llarbegin @tablefont 

                                               ignorespaces @sharp uns...



LT@mcol ...def @sharp {#3}@arstrut @preamble 

                                                  null ignorespaces 

...

l.7 caption{A simple longtable example}

                                         label{tab:stat} \

So in fact this is an incompatibility between dgruyter and longtable.

(The dgruyter package was taken from https://www.degruyter.com/dg/page/production-for-authors )

Addendum: The definition of @classz inside dgruyter.sty uses @tablefont but this macro isn't defined inside a longtable. For supertabular there is a patch inside dgruyter.sty but there is one missing for longtable.

So to make this short: dgruyter isn't adapted to the longtable package (yet), so use supertabular instead. In parallel you could request the adaption to longtable from the De Gruyter publisher.
