final Object[][] recorder={

jt=new JTable(recorder,tableHead);
jt.setGridColor(Color.red);
int v=ScrollPaneConstants.VERTICAL_SCROLLBAR_AS_NEEDED;
int h=ScrollPaneConstants.HORIZONTAL_SCROLLBAR_AS_NEEDED;
JScrollPane jsp=new JScrollPane(jt,v,h);
cp.add(jsp,BorderLayout.CENTER);
cp.add(jb1,BorderLayout.SOUTH);
jb1.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent ae)
