How to put JComboBox in JTable?

Question

I'm trying to put JComboBox in JTable, the following is my table model. The problem is that it doesn't display a JComboBox but a string of it, something like "MyTableModel$JComboBox....". Any help would be appreciated.
class MyModel extends AbstractTableModel {
String[] columnNames = {"Column One", "Column One"};
String[] boxItem = {"Item One", "Item Two"};
String[] rows = {"Row One", "Row Two"};
JComboBox[] boxes = {
new JComboBox(boxItem),
new JComboBox(boxItem)
Object[][] data = new Object[][]{rows, boxes};
public Object getValueAt(int row, int col) {
return data[col][row];
}

Hi,
the TableModel is the wrong place to put the combo box. A model is just a representation for the data displayed in the table.
A combo box, on the other hand, is a certain way for the user to edit the values in the table (and in the model). To change the way a user edits in a table you have to set the TableCellEditor. You can do this for the whole table or for a certain column.
// in the JTable's constructor or init method
// to set JComboBox in 2nd column
// get 2nd column
TableColumn column = myTable.getColumnModel().getColumn(1);
// create combo box
JComboBox combo = new JComboBox();
combo.add("ItemOne");
combo.add("ItemTwo");
// set as editor for the column
DefaultCellEditor editor = new DefaultCellEditor(combo);
column.setCellEditor(editor);This is just an example. Try it w/ a simple table.
