One of the features of web browsers that we enjoy exploiting is the changes to the lay-out design that come from altering the size of the browser window. We try to make all our pages pleasing, no matter what size of the window.
Naturally, we use tables a great deal as a way to organize design elements on the page. We do not subscribe to the school of page lay-out that tries to duplicate the fixed graphics of a printed page in a web format.
Please feel free to play with the width of the browser window. If we've done our job, each width will have a distinct aesthetic appeal.
