Hiding horizontal scroll bar in TDBGRID

How can I hide the horizontal scroll bar in a DBGrid??

I've tried both of the following shown below in the FormCreate event
method...

   SetScrollRange(TheMainDBGrid.Handle,SB_HORZ,0,0,FALSE);
   ShowScrollBar(TheMainDBGrid.Handle,SB_HORZ,FALSE);

... neither of which works.

The grid in question is linked to a table with multiple columns. Only one of
the columns is visible, with the column width set to less than the overall
DBgrid client width.
