The new 2-D table looks pretty good and I am VERY HAPPY with the
changes.

I have made some changes - presentation-wise - on top of your changes. I
have attached 3 screenshots that demonstrates the changes that I have
made [1]. FYI, my FSF copyright assignment number for Emacs is #618390.

I also propose that some additional changes be made to quail.el [2]. I
am unsure how to introduce these changes cleanly.
