I have a div within a table, within another table. I know there's a way to position absolute a div. Can you do this relative to it's position within the table? Can you position the table to an absolute position? If so on either, how?

Can you do this relative to it's position within the table?

Yes, using position:relative

Can you position the table to an absolute position?

Yes, using position:absolute, just like you would a DIV, but the table needs an id:

<table id="myTable">

and in your stylesheet:

#myTable { position: absolute; left: 100px; right:100px }
