Color cell in JTable

[ippacciani]

Hi,

I'm new of Java graphics and I've some problems with a JTable.
I need to change the color of cells(not of the text in the cell) only for the first 5 cells in my JTable. This color should change in a jToggleActionPerform method.
I know that a CustomTableCellRenderer is necessary but how can I use it in the method?

Is there anyone who could help me?

Thanks a lot

You may be able to achieve this without a custom renderer. Set a boolean field to the state of the JToggleButton in its actionPerformed, and repaint() the table. Then setBackground of the cell in a prepareRenderer override based on the boolean field value and the row, column parameters.

Here's a prepareRenderer override that colors table cells on the diagonal yellow:

JTable table = new JTable(data, headers) {

   @Override
   public Component prepareRenderer(TableCellRenderer renderer,
         int row, int column) {
      JLabel label = (JLabel) super.prepareRenderer(renderer, row, column);
      if (row == column) {
         label.setBackground(Color.YELLOW);
      } else {
         label.setBackground(Color.WHITE);
      }
      return label;
   }
}

Thanks a lot for your help.
I've not understood very well the question about the boolean field in jToggle button. Considering I work with NetBeans IDE and I don't create directly the jTable, how could I do for solving the question?

Thanks again
