What is the best way to vertically centre a table on the screen?

Hi there

I know that at its most basic the <CENTER> tag will horozontally centre a table (or whatever) on the screen - but what are some simple and/or CSS ways of vertically centering things?

Check out Dead Centre [wpdfd.com]. They use a one pixel high div absolutely positioned 50% from the top, then nest the content div inside of it.
