Table 1. A CALS table with a title before

X	O	X
O	X^a	O
O		X

Looks a bit like a tic-tac-toe (aka noughts and crosses), doesn’t it?

This table also has a caption. I had completely forgotten that CALS tables could have captions. They’re not formally part of CALS, just something DocBook added to all formal objects for consistency.
