How to set the background color of target cells in a jtable?

Question

I don't want to set the background color for all the cells in the jtable, just the ones I choose. How do i go about doing this?

Answer 1

you need to use a custom renderer

Answer 2

You might find the concept presented in Table Row Renderering easier to implement. Maybe keep a Set of Points (representing a cell you want to color). Or maybe even a Map of Points and Colors.

Answer 3

You'll need to create a custom CellRenderer and call it in your custom JTable's getCellRenderer(int col, int rol) method.

See http://self-reference.com/tech/swing.html for a good example.
