 It may be worth noting that having a PageCount of one is consistent
 with how the grid operates.  When there are zero items and paging is
 turned on, the list of available pages shows "1".  The page still
 exists, it just has zero items on it.

+IMHO, no need to check for a column number > 0 , just return the empty
+column array list. A zero element collection needs to be supported.
