Here's a start (I couldn't be bothered to set an editor too):import java.awt.*;
import javax.swing.*;
import javax.swing.event.*;
import javax.swing.table.*;
public class Test extends JFrame {
    public Test () {
        JTable table = new JTable (new TestTableModel ());
        table.setDefaultRenderer (Integer[].class, new TestTableCellRenderer ());
        table.setRowHeight (50);
        getContentPane ().setLayout (new BorderLayout ());
        getContentPane ().add (new JScrollPane (table));
        setDefaultCloseOperation (DISPOSE_ON_CLOSE);
        setTitle ("Test");
        pack ();
        setLocationRelativeTo (null);
        setVisible (true);
    public static void main (String[] parameters) {
        new Test ();
    private class TestTableModel implements TableModel {
        private final static int N = 10;
        private Object[][] data;
        private ColumnData[] columnData;
        public TestTableModel () {
            data = new Object[N][2];
            for (int i = 0; i < N; i ++) {
                data[0] = new Integer (i);
data[i][1] = new Integer[i + 1];
for (int j = 0; j <= i; j ++) {
((Integer[]) data[i][1])[j] = new Integer (j);
columnData = new ColumnData[] {
new ColumnData ("n", Integer.class),
new ColumnData ("0..n", Integer[].class)
public int getColumnCount () {
return columnData.length;
public int getRowCount () {
return data.length;
public boolean isCellEditable (int row, int column) {
return false;
public void setValueAt (Object value, int row, int column) {}
public Class getColumnClass (int column) {
return columnData[column].classType;
public Object getValueAt (int row, int column) {
return data[row][column];
public String getColumnName (int column) {
return columnData[column].name;
public void addTableModelListener (TableModelListener listener) {}
public void removeTableModelListener(TableModelListener listener) {}
private class ColumnData {
public String name;
public Class classType;
public ColumnData (String name, Class classType) {
this.name = name;
this.classType = classType;
private class TestTableCellRenderer extends JScrollPane implements TableCellRenderer {
private JList list;
public TestTableCellRenderer () {
list = new JList ();
setViewportView (list);
public Component getTableCellRendererComponent (JTable table, Object value, boolean selected, boolean focused, int row, int column) {
list.setListData ((Integer[]) value);
return this;
Kind regards,
