    JTable table = new JTable(data, columns);
    JScrollPane scroll = new JScrollPane(table);

    JFrame f = new JFrame();
    f.setContentPane(scroll);//from  w w  w  . j av  a 2s . c  o m
    f.pack();

    int x = (int) table.getTableHeader().getSize().getWidth();
    int y = (int) table.getTableHeader().getSize().getHeight() + (int) table.getSize().getHeight();

    BufferedImage bi = new BufferedImage((int) x, (int) y, BufferedImage.TYPE_INT_RGB);

    Graphics g = bi.createGraphics();
    table.getTableHeader().paint(g);
    g.translate(0, table.getTableHeader().getHeight());
    table.paint(g);
    g.dispose();

    JOptionPane.showMessageDialog(null, new JLabel(new ImageIcon(bi)));
