jQuery Accordion Just Not Quite Right

jQuery Accordion Just Not Quite Right

I've managed to cobble together a few decent accordion widgets--based on unordered lists. However, when I tried to graduate to making an accordion with tabular data, things kinda fell apart.

I still made it work, but only to a degree. I cannot figure out how to make any open rows close when you click on another row. Can anyone nudge me in the right direction?
