1. Select the Last column in the grid and click it to open the C1TrueDBGrid Tasks menu.
   
2. Select Column Style from the menu.
   
3. Click the Fill Effects tab.
4. Set BackColor 2 to Aqua.
5. Set Gradient mode to ForwardDiagonal.
6. Check the Gamma correction box.
   
7. Click Ok to close the Column Style(Last) dialog box.
