Merged Column Headers in Table

[#1]

Can anyone explain how to create merged column headers in a table? I.e.

Group Column Header 1     |   Group Column Header 2

Sales| Region| Country|           Product|Price|Distributor|

Right now I have ValueList(Header1, Header2) dimension and expressions conditional on ValueList(Header1, Header2)='Header 1'

but the table says all expression are disabled.

Thanks

The easiest solution is to put two text boxes for the group headers above the table.
