Ok, I believe I have it working now. My problem was that I was not trying to
do the commit in the "stopCellEditing" method of the CellEditor.
It also appears to me that using "JTable.setSurrendersFocusOnKeystroke(true)"
doesn't directly make any difference for this issue, however, I find that basic
keyboard operations on tables don't work quite correctly if it is NOT set. I
found that if I use the keyboard to navigate to cells whose editors are
spinners or comboboxes (other editor types might behave similarly), then
pressing the Spacebar sometimes does not put the cell into edit mode. However,
when I set SFOK to true, I can't find a scenario where it fails to put it into
edit mode upon pressing the Spacebar. What's even worse, when this flag is
false, when I keyboard navigated to a cell edited by a spinner, and pressed the
Spacebar, sometimes the cell would go into edit mode only "halfway". The
editor component would seem to display, but it would continue to use the
background color of the renderer label.
