Tables that extend as more content is added - bad idea?

I need to know if using tables this way is a bad idea

[DJFlite]

Ive started to redesign my site and I have a question about my new layout.

The way Ive done my new site is with a lot of DIV postioning. I positioned the 'frame' of my page (logo, adds, special feature boxes etc) around a center DIV, which will contain the context of that page. I plan to take all the content from my old pages and paste them into this DIV. Heres my question. My site has hundreds of pages, all of different lenghts. What I have done is put a single cell table into the center content DIV and given it a height equal to that of the smallest page. When I put and content into that table that takes up more room than I have given it, the table will expand accordingly. My question is whether or not this is a bad idea. Do the tables expand on all browsers? Will this cause any problems?

Thanks for you help!

Re: tables
I use tables with width defined in %, height I leave out completely = not specified. Effext is, when I optimize for 800 x 600 screen the browser will adjust width & height for bigger screens.

Of course, it makes problems for users with portable computer due to smaller screen size. I get less than 1% from those, but of course you can optimize your pages for whatever size you want. Just make it small enough. The problems come only when the browser starts pushing your page into an smaller space than it was intended for.
