Okay man,
take your main table size in percentage or give width and height in pixel, i think my advice is give your table size in percentage why because it take any resoultion of moniter it fit window size

"Once you start to seriously consider designing your Web page, rather than just throwing up a bunch of links in a bulletted list, most Web designers start to worry about what resolution to design for. And what this really ammounts to is trying to decide how wide to design your pages. "

This is a problem for everyone, and there are some ideas on the above page.
I usually use a fixed width (1024) by some prefer percentages.
There is no allowable tag for height, so don't worry about it.

well i use dreamweaver to design up one with 1250 x 1250 pixels and even on my 14 inch laptop screen it doesnt look good, where as i send it to my friend using a 22 inch monitor it look absurd.
Note* i m a newbie too a dreamweaver just started to learn recently =*

What do you mean, "It doesn't look good?"
Post a copy or a screenshot.
Don't use a height parameter. It's not supported by W3C, and 1250 is way too big for most surfers.

Here i attached how it look it after i zoom in few times and how it originally look like.

Oh man take the table width 100 percentage it fit all resolutions of screens

okay thanks i ll try and see if it works i ll keep you to up to date. thanks mate

I think first of all you need to reconsider using dreamweaver. I hate it, most people i work with hate it and the people i know who use it, use code style only.

I noticed or assume the use of tables as of what Siriyal is saying. Tables are dead baby, tables are dead! Well for design layout anyway.

You first need to have a think about your site, do you want it to look exactly the same on all sites with the same whitespace or are you happy for these parimeters to change a bit?

A fixed design is as yours is a specfic width. Fixed designs use specific widths so that the layout is of the same size no matter what the monitor resolution is. You would normally align these left or center. Imagine a block drawn on an A4 sheet of paper. Now increase that paper to A3 but leave the block at the same size. You would normally specifie the width and height of elements in pixels (px)

A liquid layout, and this is what i think your after flows to fill the entire available viewpoint. Imagine your bit of paper again with the block on the A4 sheet of paper, when you increase the paper size to A3 increase the block size to the same proportion. You would normally set the width and height of your design in % or em. It is important to take into account that a liquid layout will not change the proportions of your images and text so you will also need to space the contained elements by the same amount.

I hope this kind of makes sense, think I will go start a blog with common things like this so i can just point people towards that.

well omol i can still make changes or stuff on it hmm well let me point out something first this is just my second time using dreamweaver. when you say reconsider using dreamweaver do you mean that i shud use html to write it ?? i have just a little knowledge bout HTML. hm and siriyal how to change the table width from html side i m a bit confused now
