How to set the width of the table according to screen resolution

[psspl]

hello friends,

I am developing a website, in which i have put up a table. I have divided it in 3 parts left coloumn,center body and right coloumn.
I know how to do the positioning using %.but my problem is in the center body the Image i put gets distorted coz of using % in high screen resolutions.
I want to keep the center body of fixed size 900 px. and the left and the right coloumn should vary according to the screen resolution.

Is their any solution to this problem.I got this idea from "orkut.com". where the same concept is used.

Thanx in advance.Plz reply soon to my problem.

Have a look at this:

It's all css. It doesn't have much to do with screen resolutions as it does with the available viewport.

Post back if you have any problems.
