Coloring a table cell with swing

Question

Hello,
I am trying to write a java program in swing. Basically I am setting up a table and adding labels to the table's cells. Rather than displaying the label, the table is inserting the labels' string value. Here is a compilable example:
import java.awt.GridBagLayout;
import java.awt.GridBagConstraints;
import java.awt.Insets;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JTable;
import javax.swing.JScrollPane;
import java.awt.*;
public class TableTest extends JFrame {
     private final JTable table;
     private final GridBagConstraints constraints;
     private JLabel makeLabel(Color c){
          JLabel lab = new JLabel(" ");
          lab.setOpaque(true);
          lab.setBackground(c);
          //getContentPane().add(lab, constraints);
          return lab;
     public TableTest() {
        super("Visualizer");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        getContentPane().setLayout(new GridBagLayout());
        constraints = new GridBagConstraints();
        constraints.insets = new Insets(3, 10, 3, 10);
        String[] columnNames = {"RED","YELLOW", "BLUE"};
        Object[][] data = { {makeLabel(Color.RED), makeLabel(Color.YELLOW), makeLabel(Color.BLUE) } };       
        table = new JTable(data, columnNames);
        table.setPreferredScrollableViewportSize(new Dimension(500, 70));
        table.setFillsViewportHeight(true);
        JScrollPane scrollPane = new JScrollPane(table);
        //Add the scroll pane to this panel.
        add(scrollPane);
        pack();
        setVisible(true);
     public static void main(String[] args) {
          new TableTest();
}How do i modify this to actually show the labels? Thanks in advance.

Why are you putting labels into the table's cells?
Have a look at Sun's tutorial on tables to see how a custom renderer is used to display particular cells in a certain way. (And also for the whole rendering approach used by tables.)
