HELP!!!Embedding a JTable on a ScrollPane into a JTable's cell

Question

I have a single column DND JTable on a DND JScrollPane that I would like to put into another's JTable's cell. I've tried creating a CellRenderer that extends the DNDJScrollPane and returns this but this doesn't work. I do have code I could post if anyone is interested in helping out.

Answer 1

First copy this and compile and run and c.. then look at the code
import javax.swing.border.*;
import javax.swing.event.*;
import javax.swing.table.*;
import java.awt.event.*;
import javax.swing.*;
import java.util.*;
import java.io.*;
import java.awt.*;
public class JTableExample extends JFrame
JTableRenderer renderer;
MyTableModel m1, m2;
public JTableExample()
super();
m1 = new MyTableModel();
m2 = new MyTableModel();
DefaultTableModel dtm = new DefaultTableModel()
// make first cell uneditable
public boolean isCellEditable(int row, int column)
return !(column == 0);
dtm.setDataVector(new Object[][]{{ "JTable1",  m1},
{ "JTable2",  m2}},
new Object[]{ "Column1","Column2"});
JTable table = new JTable(dtm);
renderer = new JTableRenderer();
table.getColumn("Column2").setCellRenderer(renderer);
table.getColumn("Column2").setCellEditor(new JTableEditor());
table.setRowHeight(80);
JScrollPane scroll = new JScrollPane(table);
getContentPane().add(scroll);
setSize( 400, 250 );
setVisible(true);
public static void main(String[] args) {
JTableExample frame = new JTableExample();
frame.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
System.exit(0);
* JTable Editor
class JTableEditor extends DefaultCellEditor
public JTableEditor()
super(new JCheckBox());
public Component getTableCellEditorComponent(JTable table, Object value,
boolean isSelected, int row, int column)
return renderer;
public Object getCellEditorValue()
return (MyTableModel)((JTableRenderer)renderer).jtable.getModel();
* JTable Renederer
class JTableRenderer extends JScrollPane implements TableCellRenderer
JTable jtable;
public JTableRenderer()
jtable = new JTable();
getViewport().add(jtable);
public Component getTableCellRendererComponent(JTable table, Object value,
boolean isSelected, boolean hasFocus,
int row, int column)
if (isSelected)
setForeground(table.getSelectionForeground());
setBackground(table.getSelectionBackground());
jtable.setForeground(table.getSelectionForeground());
jtable.setBackground(table.getSelectionBackground());
else
setForeground(table.getForeground());
setBackground(table.getBackground());
jtable.setForeground(table.getForeground());
jtable.setBackground(table.getBackground());
jtable.setModel((AbstractTableModel)value);
return this;
class MyTableModel extends AbstractTableModel {
final String[] columnNames = {"First Name",
"Last Name",
"Sport",
"# of Years",
"Vegetarian"};
final Object[][] data = {
{"Mary", "Campione",

{"Angela", "Lih",
"Teaching high school", new Integer(4), new Boolean(false)}
public final Object[] longValues = {"Angela", "Andrews",
"Teaching high school",
new Integer(20), Boolean.TRUE};
public int getColumnCount() {
return columnNames.length;
public int getRowCount() {
return data.length;
public String getColumnName(int col) {
return columnNames[col];
public Object getValueAt(int row, int col) {
return data[row][col];
public Class getColumnClass(int c) {
return getValueAt(0, c).getClass();
public boolean isCellEditable(int row, int col) {
if (col < 2) {
return false;
} else {
return true;
public void setValueAt(Object value, int row, int col) {
if (data[0][col] instanceof Integer
&& !(value instanceof Integer)) {
try {
data[row][col] = new Integer(value.toString());
fireTableCellUpdated(row, col);
} catch (NumberFormatException e) {
} else {
data[row][col] = value;
fireTableCellUpdated(row, col);

cheers
good luck
