Empty Rows in a table

[Karen Davis]

Does anyone know if it is possible to add empty rows into a JTable, even if there is no data to display???

Hi Karen,
Not to a JTable, but you can to its model:

import javax.swing.*;
import javax.swing.event.*;
import javax.swing.table.*;
import java.awt.*;
import java.awt.event.*;
public class EmptyTableTest extends JFrame {
  final int initialRowQty = 3;
  DefaultTableModel dtm = null;
  JTable jt = null;
  String [] names = {"X", "Y"};
  Object [][] data = null;
  EmptyTableTest () {
    data = new Object [initialRowQty][];
    for (int i = 0; i < initialRowQty; i++) {
      data [i] = new Object [names.length];
    }
    Container c = getContentPane ();
    dtm = new DefaultTableModel (data,names);
    jt = new JTable (dtm);
    JScrollPane jsp = new JScrollPane (jt);
    c.add (jsp);
    JButton jb = new JButton ("Add Empty Row");
    c.add (jb, BorderLayout.SOUTH);
    jb.addActionListener (new ActionListener () {
      public void actionPerformed (ActionEvent ae) {
        doButton ();
      }
    });
    pack ();
    setSize (300,200);
    setVisible (true);
    addWindowListener( new WindowAdapter() {
      public void windowClosing( WindowEvent e ) {
        System.exit(0);
      }
    });
  }
  void doButton () {
    Object [] d = new Object [names.length];
    dtm.addRow (d);
  }
  public static void main (String [] args) {
    new EmptyTableTest ();
  }
}
