JTable: set different cellEditors for cells within a column

Question

I have a table that there could be different class types within the same column, such as Integer, String. How could I invoke different editors based on the class type from the cell? I would appreciate it for your help.

Answer 1

Thanks very much! However, after editoring, the returned value is always a String. How do I preserve the original class type from the cell? I copied the following codes from somewhere, but can I have just one number editor for both Integer and Double classes?
public class NumberEditor extends DefaultCellEditor{
public NumberEditor(JTextField t) {
super(t);
setClickCountToStart(2);
public Object getCellEditorValue() {
return new Integer/Double((String) delegate.getCellEditorValue());
