But this is a technical restriction. A fixed witdth is required for
automatic line wrapping. With manual line-breaks the column width can be
calculated from the maximal line length.
However, LaTeX does not allow manual line-breaks in a table cell.
A workaround is to use the \shortstack macro (currently as ERT).
This would lead to e.g. the following LaTeX source:
\begin{tabular}{|c|>{\centering}p{3cm}|}
\hline
\shortstack{not so\\short\\stack} & fixed\\
width\tabularnewline
\hline
\end{tabular}
The vertical alignment needs some improvement, but generally this works.
It would be nice if LyX could interpret a Ctrl-Enter in a variable-width
table cell as "insert the content in a \shortstack with a line-break at
this place".
