I've roamed the web for two afternoons looking for info on Excel
2003's autofiltering.  Pages that might spell out the boundaries of
the filtering functionality.  For example:

* That the filtering range is bounded at the bottom by a blank line
* That the down-arrows appear on the cells in the selected row when
filtering is turned on
* A clearer description of how to filter for different values across
the different columns.  I've tried following the illustrated examples
on the web, MS site, and helpfiles...I'm obviously not doing it right.

Thanks for any referrals to online resources I might have missed.
