DataTable is next to RowHeaderTable. Select a cell of DataTable in row 1. The same row 1 of RowHeaderTable change Fore-/Background (for example Color.GREEN/Color.ORANGE).
Now select a cell of DataTable in row 0 and RowHeaderTable change Fore-/Background of row 0 to Color.GREEN/Color.ORANGE and row 1 of RowHeaderTable change Fore-/Background to default-Colors.
How can I change Fore-/Background of cells in each row of RowHeaderTable?
