Change the background color of a row in a JTable
I have a JTable with 3 columns. I've set the `TableCellRenderer` for all the 3 columns like this (maybe not very effective?).
      
     for (int i = 0; i < 3; i++) {
         myJTable.getColumnModel().getColumn(i).setCellRenderer(renderer);
     }

The `getTableCellRendererComponent()` returns a Component with a random background color for each row.  
How could I change the background to an other random color while the program is running?
