Resetting priveleges on a table

I have a database that has a few tables that have privileges granted by 
a user that no longer works here.  I am the owner of these tables and 
the owner of the database.  If I do any granting/revoking on these 
tables my actions do not seem to affect the privs set by this other 
user.  The privileges I have set show up after the original user 
privileges in the \z output.

How can I clean this up.  Would dropping the user have any effect?

This is on 7.4 if that makes a difference.
