can somebody confirm? a cell is like:
-------------------------snip---------------- <row topline="true" bottomline="false" endhead="false" endfirsthead="false" endfoot="false" endlastfoot="false" newpage="false"> <cell multicolumn="0" alignment="left" valignment="top" topline="true" bottomline="false" leftline="true" rightline="false" rotate="false" usebox="minipage" width="0pt" special=""> \begin_inset Text \layout Standard \added_space_top 1cm \added_space_bottom 1cm my minipage \end_inset -------------------------snip---------------- which should give an latex export like \begin{minipage}[t]{4cm} \vspace{1cm} my minipage% \vspace{1cm} \end{minipage}& but LyX ignores both vertical spaces! demo is attached Herbert -- http://www.lyx.org/help/
