Can I remove the sort option from the column headings? In my grid (4 columns) I see "3" <up arrow> on the second and 4 <up arrow> on the third column, but nothing like it on the 1st or 4th. Both of them are renderers so I'll assume that is the reason, but I would like to verify it. All of them have the vertical line for the sort.
I'd like to remove that on the first. TIA, Jerry
