Hi,
See this demo pasted below-
import java.awt.*;
import javax.swing.*;
public class SimpleTableDemo extends JFrame {
     public SimpleTableDemo() {
          super("SimpleTableDemo");
          Object[][] data = {
               {"Mary", "Campione", "Snowboarding", new Integer(5), new Boolean(false)},
               {"Alison", "Huml", "Rowing", new Integer(3), new Boolean(true)},
               {"Kathy", "Walrath", "Chasing toddlers", new Integer(2), new Boolean(false)},
               {"Sharon", "Zakhour", "Speed reading", new Integer(20), new Boolean(true)},
               {"Angela", "Lih", "Teaching high school", new Integer(4), new Boolean(false)}
          String[] columnNames = {"First Name", "Last Name", "Sport", "# of Years", "Vegetarian"};
          final JTable table = new MyTable(data, columnNames);
          table.setPreferredScrollableViewportSize(new Dimension(500, 70));
          JScrollPane scrollPane = new JScrollPane(table);
          getContentPane().add(scrollPane, BorderLayout.CENTER);
     public static void main(String[] args) {
          SimpleTableDemo frame = new SimpleTableDemo();
          frame.pack();
          frame.setVisible(true);
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class MyTable extends JTable {
     public MyTable(Object[][] rowData, Object[] columnNames) {
          super(rowData,columnNames);
     public String getToolTipText(MouseEvent e) {
          int r = rowAtPoint(e.getPoint());
          int c = columnAtPoint(e.getPoint());
          return getValueAt(r,c).toString();
}
