How could I make a list look like a table, that automatically extends when info is added?

I know how to make it look like a table, and I know how it would grow when info is added, but the problem is the table's border is rounded and has a header area to it. I was开发者_运维百科 thinking of making it a background image but I don't know how I could get it to grow while keeping the rounded corners..

Any ideas would be very helpful

To make it grow you have to set the rounded corners as separate backgrounds. In html 5 this is a lot easier, however for the current usage you can check out here

This is an old site, that still works. This can also be done with javascript that doesn't use any images, there are lots of options depending on your end goal.

Are you wanting to grow width or height? Adding columns or rows? Are you going to use <table> or <div> tags?

Or are thinking of using accordions that expand upon user click JS Accordions
