OK, here's an example off the top of my head:

// Create a renderer to color a row
class MyTableCellRenderer extends DefaultTableCellRenderer { 
   public Component getTableCellRendererComponent(JTable table, 
                     Object value,
                     boolean isSelected,
                     boolean hasFocus,
                     int row,
                     int column) { 
   // let the superclass do all the work
   Component renderer = super.getTableCellRendererComponent(
                  value, isSelected, hasFocus, row, column);
   // Change background to the required color 
   // if this is the required row
   if (row == requiredRow) {
      renderer.setBackground(requiredColor);
   }
   return renderer;
}

...

// Set this renderer for all class types (i.e. columns) in the table
myTable.setDefaultRenderer( Object.class, new MyTableCellRenderer());

This is untested code, but it shows the basic technique.

The higher, the fewer...
