I guess I can answer this as the unofficial keeper of Table.
Table has some very major and fundamental flaws in geometry management (as
do a number of other widgets, unfortunately).  I recently did a nearly
complete rewrite of the geometry management code and will be releasing
this sometime in May.

This said, I'm not sure that's your problem.

The new table keeps an idea of what the preferred size of the child
was, so it should come back at that size, as long as the child doesn't
make any stupid resize requests.

A lot of composite widgets are pretty bad about shrinking.  The old Table
didn't even try.  The new one does, although it's not terribly smart
(I'd like it to shrink proportionally).

I'm not sure why mapping doesn't work.  Unmapping the widget ought
to leave a blank space where it was.  Remapping will bring it back.
There shouldn't be any geometry changes.

I'm not sure which upsets me more: that people are so unwilling to accept
responsibility for their own actions, or that they are so eager to regulate
everyone else's.
