I'm using the tabular enviroment \begin{tabular}
... \end{tabular}
inside of the beamer class \begin{frame}
... \end{frame}
tags.
In standard latex documents, i often use something like
\begin{tabular}{C{2.5cm} C{1cm} C{1.5cm} C{1.5cm} C{1.5cm} C{1.5cm} C{1.5cm} C{1.5cm} C{1.5cm} C{1.5cm}}`
to predefine column widths. This seems not to work inside of beamer frames, i get the error:
! Package array Error: Illegal pream-token (C): `c' used.
Replacing 'C' with 'c' leads to:
! Package array Error: Illegal pream-token (2.5cm): `c' used.
Why does the interpreter complains about setting the width? Is there a universal solution to handle that issue in general?
