The second reason is that with array the argument to \begin{tabular} is not expanded, the third is that even if expansion was peformed, it wouldn't work, because \ifthenelse is not “fully expandable”. Put the \ifthenelse outside: \newenvironment{mymulticolumn}[3][2] {% \renewcommand{\arraystretch}{#1}% \ifthenelse{#2=2} {% \begin{tabular}{@{} x @{\cs} p{#3} x @{\cs} l}% } {% \begin{tabular}{@{} x @{\cs} p{#3} x @{\cs} p{#3} x @{\cs} l}% }% }% {\end{tabular}} share|improve this answer answered Dec 31 '14 at 20:37 egreg 514k5913792437 add a comment| Your Answer draft saved draft
