My application has a JTable with a custom editor defined on one of the columns.  What I'd like to do is to disable the JTable from selecting the next line when the user hits the Return key.  I know that pressing the Return key commits the change to the data being displayed.  I want to prevent the JTable from changing the selection to the next line after committing the change.  Is this possible?  If so, how do I do it? If you can, please either include a code snippet in your reply or point me to where I can see some code that does this.  Thanks in advance.

What I do is this:
I  make a KeyListener and put an if:

if (myTable.isFocusOwner() && e.getKeyCode() == 10)

the code 10 is for the return key. Next, you get the selected row(it will be the next you selected) and create an object to select your own row. The last step is select the interval (rows). As the JTable selects the next row when you press enter key, you only need to select the previous row and it appears that nothing happened. (Actually the JTable has selected again the row  where user hits return key but you don't notice this)
public void keyPressed(KeyEvent e) {
    if (myTable.isFocusOwner() && e.getKeyCode() == 10) {
        int selectedRow = myTable.getSelectedRow();
        ListSelectionModel selectionModel = myTable.getSelectionModel();
        selectionModel.setSelectionInterval(selectedRow - 1, selectedRow - 1);
