But remember, that's easier said than done.  You might have word wrap in
every cell going across.  For this to work, you would have to be doing
that word wrapping on every cell in parallel.  When one cell detects
that it's about to exceed the page, you'd need to send a signal to all
of the other cells telling them to fill out as much as they can, then
pause until after the page break, then resume.  And what about paragraph
widow control?  That requires backtracking.

There's a lot of state to carry around.
