I worked undo/redo function on a jTextField using code below. I tried to add UndoableEditListener to jTable but I got nothing.
When you add a row to the table with wrong details then you should be able to erase that row usingControl + Z as well as you press Control + Y the same row should be visible in the jTable with early mentioned values also. I think it's not implementing a CellEditor. Please help me on this.

final UndoManager undo = new UndoManager();
JTextField jTextField1 = new JTextField();
Document doc = jTextField1.getDocument();
doc.addUndoableEditListener(new UndoableEditListener() {

public void undoableEditHappened(UndoableEditEvent evt) {
undo.addEdit(evt.getEdit());
}
});
jTextField1.getActionMap().put("undo", new AbstractAction("undo") {

public void actionPerformed(ActionEvent arg0) {
try {
if (undo.canUndo()) {
undo.undo();
}
} catch (CannotUndoException e) {
}
}
});
jTextField1.getInputMap().put(KeyStroke.getKeyStro ke("control Z"), "undo");
