How to not show one column's heading in a multicolumn listbox

[TravelingCat]

Hello,
I'm wondering whether it's possible to not show one specific column's heading in a listbox, does anyone know?
My column heads property is set to yes, but there's one column, ordinal number, and i want its heading to be empty.

You can do it in the sql of the combox

Example:

Select field1,field2,f ield3 as ' ' from table [bla bla bla]
