How to set cell background color for JCheckBox renderer in JTable?

Question

I need to display table one row with white color and another row with customized color.
But Boolean column cannot set color background color.
Here is my codes.
import javax.swing.*;
import javax.swing.border.*;
import javax.swing.table.*;
import javax.swing.event.*;
import java.awt.*;
import java.awt.event.*;
import java.util.TreeSet;
public class BooleanTable extends JFrame
    Object[][] data = {{Boolean.TRUE},{Boolean.TRUE},{Boolean.TRUE},{Boolean.TRUE},{Boolean.TRUE},{Boolean.TRUE}};
    String[] header = {"CheckBoxes"};
    public BooleanTable()
        setDefaultCloseOperation( EXIT_ON_CLOSE );
        TableModel model = new AbstractTableModel()
            public String getColumnName(int column)
                return header[column].toString();
            public int getRowCount()
                return data.length;
            public int getColumnCount()
                return header.length;
            public Class getColumnClass(int columnIndex)
                return( data[0][columnIndex].getClass() );
            public Object getValueAt(int row, int col)
                return data[row][col];
            public boolean isCellEditable(int row, int column)
                return true;
            public void setValueAt(Object value, int row, int col)
                data[row][col] = value;
                fireTableCellUpdated(row, col);
        JTable table = new JTable(model);
        table.setDefaultRenderer( Boolean.class, new MyCellRenderer() );
        getContentPane().add( new JScrollPane( table ) );
        pack();
        setLocationRelativeTo( null );
        setVisible( true );
    public static void main( String[] a )
        try
            UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
        catch( Exception e )
        new BooleanTable();
    private class MyCellRenderer extends JCheckBox implements TableCellRenderer
        public MyCellRenderer()
            super();
            setHorizontalAlignment(SwingConstants.CENTER);
        public Component getTableCellRendererComponent(JTable
                                                       table, Object value, boolean isSelected, boolean
                                                       hasFocus, int row, int column)
            if (isSelected) {
               setForeground(Color.white);
               setBackground(Color.black);
            } else {
               setForeground(Color.black);
               if (row % 2 == 0) {
                  setBackground(Color.white);
               } else {
                  setBackground(new Color(239, 245, 217));
            setSelected( Boolean.valueOf( value.toString() ).booleanValue() );
         return this;
}

Instead of extending JCheckBox, extend JPanel... put a checkbox in it. (border layout center).
Or better yet, don't extend any gui component. This keeps things very clean. Don't extend a gui component unless you have no other choice.
private class MyCellRenderer implements TableCellRenderer {
    private JPanel    _panel = null;
    private JCheckBox _checkBox = null;
    public MyCellRenderer() {
        //  Create & configure the gui components we need
        _panel = new JPanel( new BorderLayout() );
        _checkBox = new JCheckBox();
        _checkBox.setHorizontalAlignment( SwingConstants.CENTER );
        // Layout the gui
        _panel.add( _checkBox, BorderLayout.CENTER );
    public Component getTableCellRendererComponent(JTable table, Object value,
        boolean isSelected, boolean hasFocus, int row, int column) {
        if( isSelected ) {
           _checkBox.setForeground(Color.white);
           _panel.setBackground(Color.black);
        } else {
           _checkBox.setForeground(Color.black);
           if( row % 2 == 0 ) {
              _panel.setBackground(Color.white);
           } else {
              _panel.setBackground(new Color(239, 245, 217));
        _checkBox.setSelected( Boolean.valueOf( value.toString() ).booleanValue() );
        return _panel;
}
