No -- the decision to not support nested tables was and is a conscious 
design decision on my part, and not because of any limitations
imposed by the line-by-line implementation of the markup algorithm.  
I could've just as easily created a nested table algorithm, but I 
deliberately chose not to because I didn't like the way it complicates 
the markup from an authoring perspective.

(The proof that nested structures can be handled line-by-line is
demonstrated by the various list markups, which properly nest even
in the face of different nesting levels and nesting types.)
