I'm making a left-side navigation with content to the right, and I want those two to be separated by a single line. When I set the navigation table's border equal to one, how do I tell it I only want the right side to have a line and the rest not?

CSS. For example, if you don't have an external style sheet

<table style="border-right: 1px solid #000;">

But I would recommend doing layout with <div>'s and CSS. Tables are for tabular data.

yup that's how u do it

Even better, dump the table and do it ALL with CSS
