[Javascript] Non-Scrolling Titles

[pd]

Is there a way to create something like an html <table> with javascript 
that keeps the title row stationary at the top while allowing the other 
rows to scroll up underneath it?  It would need to use the vertical scrollbar.

I need to create reports with the top line stationary and the bottom rows 
scrolling up.

It seems like I've seen this on different web sites.  It seems like it 
would already have been done somewhere.

If not with javascript, is there another technology that would make it 
possible?

Thank you for any ideas you might have.  Much appreciated.
