I have just been playing with a demo portal at demo.dotnetnuke.com, and was wondering if it's possible to apply a filter to the user defined table.  For instance, i would like to add a field called Category, and allow the user to choose a category from say a pull down list and have the table filtered.

Another use of this feature would be to apply paging against the first letter of the sort field, rather than against a number of items.  E.g. the user select a letter A through Z, and all rows with the sort field starting with this letter are displayed.

Is any of this possible?  Thanks, Stephen.
