Grouped output

hello,

Suppose I have a table that looks like this:

center name email
Health Jon [email protected]
Health Bob [email protected]
Admin Jane [email protected]
Admin Jill [email protected]

I would like the output to look like this:

Health
Jon [email protected]
Bob [email protected]
Admin
Jane [email protected]
Jill [email protected]

when i using cold fusion, this was easy via a tag called cfoutput.
when i was using java, this was difficult, and i had to put some extra
conditionals in the table. is there an easy way to do this in rails?

thanks,
Jin
