(:table border=1 :) (:cellnr:)single line (:cell:)first line\\ second line (:cell:)first line\\ second line\\ third line (:tableend:)
This used to work in the earlier versions, but is broken now. Pdflatex aborts with the following error message:
! Missing } inserted. <inserted text> } l.81 first line\\s econd line}&{\small ? ! Emergency stop. <inserted text> } l.81 first line\\s econd line}&{\small No pages of output.
(:table border=1 :) (:cellnr:)single line (:cell:) first line\\ second line (:cell:) first line\\ second line\\ third line (:tableend:)
if (preg_match('/^[^\n]+\n$/',$contents)) $SimpleColspan = (!strstr($contents, '<newline'));
Note that such cells then cannot span multiple columns.
Fixed in version 2.2.13 released Sunday, 2 August 2009 (also fixes the problem of long simple cells not correctly wrapping).
