[Docutils-develop] tables without tgroups

[Jason D. <ja...@in...>]

I'm working on a new directive which builds a table but I've run into a 
small issue that I wanted to share with the list.

If I add a table without a tgroup to a document, the html writer fails 
with a "pop from empty list" error. The pseudoxml writer works OK. If I 
add an empty tgroup to the table, the writing doesn't fail but now I 
have an empty colgroup element in the HTML.

Should the html writer really require a tgroup even if it has no colspec 
elements?

I'm using the 3.3 release.
