This is the code i m using
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.table.*;
public class TableTest extends JFrame implements ActionListener
     JButton btnAdd;
     BorderLayout layout;
     DefaultTableModel model;
     JTable table;JButton btexcluir;
     public static void main(String[] args)
          TableTest app = new TableTest();
          app.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
     public TableTest()
          super("Table Example");
          btnAdd = new JButton("Add");
          btnAdd.addActionListener(this);
          model = new DefaultTableModel()
               public Class getColumnClass(int col)
                    switch (col)
                         case 1 :
                              return Boolean.class;
                         default :
                              return Object.class;
          table = new JTable(model);
          table.setPreferredSize(new Dimension(250,200));
          // Create a couple of columns
          model.addColumn("Col1");
          model.addColumn("Col2");
          JCheckBox cbox = new JCheckBox();
          // Append a row
          JPanel painel = new JPanel();
          model.addRow(new Object[] { "v1",new Boolean(false)});
          model.addRow(new Object[] { "v3", new Boolean(false)});
          JScrollPane scrollPane = new JScrollPane(table);
          scrollPane.createVerticalScrollBar();
          btexcluir= new JButton("Excluir");
          btexcluir.addActionListener(this);
          painel.add(btexcluir);
          painel.add(btnAdd);
          getContentPane().add(scrollPane, BorderLayout.NORTH);
          getContentPane().add(painel, BorderLayout.SOUTH);
          setSize(600, 600);
          setVisible(true);
     public void actionPerformed(ActionEvent e)     {
       if (e.getSource() == btnAdd)     
          model.addRow(new Object[] { "Karl", new Boolean(false)});
       if (e.getSource()==btexcluir){
            for (int i=0; i <=model.getRowCount(); i++){
                 if (model.getValueAt(i,1)==Boolean.FALSE)
                      JOptionPane.showMessageDialog(null, "No lines to remove!!");
                 else if(model.getValueAt(i,1)==Boolean.TRUE)
                      model.removeRow(i);
}Please reply me with code help.
