Locked Header Question

Hi, all…

I’m sure this is very simple, but I was wondering how to keep a header stationary while scrolling down a page. I’m using a table layout in Dreamweaver MX, and have an embedded .swf for the header, using html (in order to disable the “click to activate control” function). If anyone could shed some light, I’d greatly appreciate it.

Thank you,
