expanding layout to fill the screen width Options

[mottwsc]

I have some information laid out with a fixed width table in html. It looks fine on a regular monitor. When I display it on a wider monitor, or with a different resolution, I have extra unused space on the right. This, of course, makes sense.

The question is: what is the recommended method for allowing the text and images to fill out the rest of the screen width - especially where it will work with different monitors, resolutions and browsers?

Thanks.
