Just create a user module (or content item) an insert a table into it.
don't you know? Joomla makes us lazy. too lazy in fact to try typing "table module joomla" into say... google. 
try this. it's a component that uses a mambot for displaying the tables you build in the component. pretty slick actually.

back to the lazy thing though, if Rocket Theme's going to release templates with 20 different color schemes, a slew of module styling options, and countless other quick customization features, what's going to be left for deisngers to do except for ediiting the logo image?
