Is it possible to buffer the entire JTable for JScrollPane scrolling?

Question

With the following code, when you scroll up and down you get lots of "called" output.
I will know when my jtable is updated, so is there
some way I can get the scrollpane to buffer the entire jtable component
so that subsequent scrolling just does drawing of the appropriate part
of the jtable from a buffered image? Note that the cells still need to
be editable (I've got cell editors). Possible? Here's the code :
public class TableBufTest {
    public static void main(String[] args) {
        String[][] data = new String[30][2];
        for (int i=0; i<2; i++) {
            for (int j=0; j<30; j++) {
                data[j] = Integer.toString(j*10 + i);
String[] columnNames = new String[] {"1", "2"};
final JLabel jLabel = new JLabel();
JTable table = new JTable(data, columnNames);
table.getColumnModel().getColumn(0).setCellRenderer(new TableCellRenderer() {
public Component getTableCellRendererComponent(JTable table, Object value,
boolean isSelected, boolean hasFocus,
int row, int column) {
System.out.println("called");
jLabel.setText((String) value);
return jLabel;
JScrollPane scrollPane = new JScrollPane(table);
JFrame jFrame = new JFrame();
jFrame.getContentPane().add(scrollPane);
jFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
jFrame.setSize(200,200);
jFrame.setLocation(300,300);
jFrame.show();
Thanks!

Thanks.
I ended up doing a couple of things - first of all using JLabels instead of JTextFields
and then creating my own FastJLabel using the DefaultTableCellRenderer as a basis.
(I couldn't use it because I have to return different components for different rows.)
