jTable1.getColumn("Con1").setCellRenderer(new ButtonRenderer());
jTable1.getColumn("Con1").setCellEditor(new ButtonEditor(new JCheckBox()));

import javax.swing.table.*;
/** * @version 1.0 11/09/98 */
public class ButtonEditor extends DefaultCellEditor {
protected JButton button;
private String label;
private boolean isPushed;
private int rowcount;

public ButtonEditor(JCheckBox checkBox) {
super(checkBox);
button = new JButton();
button.setOpaque(true);

button.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
fireEditingStopped();}});
}

public Component getTableCellEditorComponent(JTable table, Object value,
boolean isSelected, int row, int column) {
rowcount = row;
if (isSelected) {
button.setForeground(table.getSelectionForeground());
button.setBackground(new Color(182, 208, 200));
//button.setBackground(table.getSelectionBackground());
} else{
button.setForeground(table.getForeground());
//button.setBackground(new Color(184, 208, 200));
//button.setBackground(new Color(212, 208, 200));
button.setBackground(table.getBackground());
}
label = (value ==null) ? "" : value.toString();
button.setText( label );
isPushed = true;
return button;
}

public Object getCellEditorValue() {
if (isPushed) {
//
//JOptionPane.showMessageDialog(button ,label + ": tOuch!");
// System.out.println(label + ": Ouch!");
}
isPushed = false;
return new String( label ) ;
}

public boolean stopCellEditing() {
isPushed = false;
return super.stopCellEditing();
}

protected void fireEditingStopped() {
super.fireEditingStopped();
}
