I've noticed that some website have their page set in a table (I guess) that defaults to the right position when I open it in a minimized window.
Basically, even though my window is minimized, I get to see all the contents of the page and I don't have to scroll to see anything else.

Anyone know what I mean?
Thanks :)

I think they just have aligned the table to the right

like this align="right" added to the <table> code

when the window get's maximized the table will move to the right side

So how do you know what size to make the table so that it fits most browsers when their window is not fully maximized?

Just use percentages instead of absolute sizes :) So instead of width="100", use width="40%", for example. Then the table will/should automatically resize to fit within the browser window.
