Which takes us back to the begining of the discussion.. and Ziya's first
comment :-)

Thus the need for Leah to provide more information about the users (what
they know, what do they usually use, etc), about the data (how large, what
kind, local ?), and the technology (speed overheads, caching etc..) that is
going to support the application.. without which, any advice will be
extremely limited based on pressumptions for the above :-)

Only if the data is locally cached, and page reload and/or a trip to the
database is not the result of the click.

I once had to look into the face of a UI designer in utter disbelief when
she specced this very behavior without understanding the consequences of
clicking a sort button on a live data display (financial app) where the
backend was tied to a 3 terabyte database. The DB admin wasn't too keen on
this 'usability enhancement' being exercised incessantly by the users, to
say the least.:-)
