I need to know how much disk space a table is using in SQL Server

I think most people know how to do this via the GUI (right click table, properties), but doing this in T-SQL totally rocks.

Check out this, I know it works in 2005 (Microsoft Documentation):

Here is is for the pubs DB 


select *
from pubs.sys.database_files

Returns the size and max_size.
