Problem with JTable

[Sergio Zuniga]

I have a simple table model and the problem i have is that my table doesen't show the columns names(i have a String[] with te columns, and they are ok).. i don't know what happened..
The table shows OK, but the columnNames are not OK.
any ideas ??
thanks

for the column names to appear, the table has to be added to a scrollpane.

I have something like this..

JScrollPane scrollPane = new JScrollPane(table);
add(scrollPane);
JPanel1.add(table);

thanks

depending on where you want the table added, one of these lines is wrong
add(scrollPane);
JPanel1.add(table);

either
add(scrollPane); or
JPanel1.add(scrollpane);

but not both

it could even be this
JPanel1.add(scrollpane);
add(JPanel1);

here's a simple example program

import java.awt.*;
import javax.swing.*;
import javax.swing.table.*;
 
class Testing extends JFrame
{
  public Testing()
  {
    setLocation(400,100);
    setDefaultCloseOperation(EXIT_ON_CLOSE);
    String colNames[] = {"Name", "Age"};
    Object[][] data = {{"joe","21"},{"fred","31"},{"mary","22"}};
    DefaultTableModel dtm = new DefaultTableModel(data,colNames);
    JTable table = new JTable(dtm);
    JScrollPane sp = new JScrollPane(table);
    sp.setPreferredSize(new Dimension(300,100));
    getContentPane().add(sp);
    pack();
  }
  public static void main (String[] args){new Testing().setVisible(true);}
}
