dear farhanaj ,

import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
import javax.swing.table.*;
/* <applet code=tableadd.class width=200 height=200>
</applet>
public class tableadd extends JApplet implements ActionListener
Object[] data = new Object[5];
DefaultTableModel defaulttablemodel = new DefaultTableModel();
JTable jtable=new JTable(defaulttablemodel);
JPanel jpanel= new JPanel();
private     JPanel          topPanel,jpPanel;
public     JTable          table;
JButton jbutton1 = new JButton("create new row");
JButton jbutton2 = new JButton("create new col");
//JButton jbutton1=new Jbutton("r"),jbutton2=new Jbutton("c");
public tableadd()
for(int column=0 ; column<5 ; column++)
defaulttablemodel.addColumn("column" + column);
for(int row=0 ; row<5;row++)
for(int column=0 ;column<5;column++)
data[column]="cell" row "," + column;
defaulttablemodel.addRow(data);
//getContentPane().add(new JScrollPane(jtable) ,BorderLayout.CENTER);
//getContentPane().add(new JPanel() ,BorderLayout.SOUTH);
int v=ScrollPaneConstants.VERTICAL_SCROLLBAR_AS_NEEDED;
int h=ScrollPaneConstants.HORIZONTAL_SCROLLBAR_AS_NEEDED;
JScrollPane jsp = new JScrollPane(jtable , v, h);
getContentPane().add(jsp, BorderLayout.CENTER);
topPanel = new JPanel();
jpPanel=new JPanel();
topPanel.setLayout( new BorderLayout() );
getContentPane().add(topPanel,BorderLayout.NORTH);
getContentPane().add(jpPanel,BorderLayout.SOUTH);
jpPanel.add(jbutton1);
jpPanel.add(jbutton2);
jbutton1.addActionListener(this);
jbutton2.addActionListener(this);
public void actionPerformed(ActionEvent e)
if (e.getSource() == jbutton1)
int numberrows = defaulttablemodel.getRowCount();
int numbercolumns=defaulttablemodel.getColumnCount();
Object[] data = new Object[numbercolumns];
for(int column=0 ; column<numbercolumns;column++)
data[column]="cell" numberrows "," +column;
defaulttablemodel.addRow(data);
else
if (e.getSource() ==jbutton2)
int numberrows=defaulttablemodel.getRowCount();
int numbercolumns=defaulttablemodel.getColumnCount();
defaulttablemodel.addColumn("column" + numbercolumns);
for(int row=0; row<numberrows ; row++)
defaulttablemodel.setValueAt("cell" row "," +numbercolumns ,row , numbercolumns);
               System.out.println(row);
//jtable.sizeColumnsToFit(0);
