Wouldn't it be sufficient and more desirable to require each row to  
have at least one cell that starts on that row and each column to  
have at least one cell that starts in that column? (By starts I mean  
having the top left corner there.)

This would allow tables like this:
112
344
and
12
13
43
(Where numbers denote cells so that 11 means a cell spanning two  
columns.)

Browsers don't choke:
