For example, say I have a 700 pixel wide main table for a web page, would you prefer it to be docked to the left of the screen or in the centre?

Please vote on the poll and give reasoning.

I ask this because up til now I've been creating web designs where the table is centre aligned, but I've seen a few web pages with the main table left aligned and just some 'space' with maybe a page background in the remaining space. It looks effective so I thought i'd try it...so I thought I'd ask you guys what you prefer .
