How do I apply cell styles?

I'm sorry if I'm being dense, but I've created a table style with two possible cell styles. How do I apply my chosen cell style to selected elements in the table?

OK, I have figured it out, and how to create headers. For anyone else in my predicament - that display of the table in the edit table dialog is not just for measurements... that's where you apply styles.

Having figured it out... I kinda like it.
