Gets the logical layout of the table as a rectangular grid of
cells. It considers rowspan and colspan. A cell with a large
span is represented in the grid by being referenced several times.
The tablePortition parameter can get just a <thead>, <tbody>, or
<tfoot> portion if you pass one.
Note: the rectangular grid might include null cells.
This is kinda expensive so you should call once when you want the grid,
then do lookups on the returned array.
