Comment 2 for bug 1196089

http://sphinx-doc.org/rest.html#rst-tables and the linked http://docutils.sourceforge.net/docs/ref/rst/restructuredtext.html#simple-tables say "Simple tables (ref) are easier to write, but limited: they must contain more than one row, and the first column cannot contain multiple lines." and "Simple tables allow multi-line rows (in all but the first column)" respectively. I believe that's the problem.
