How do I enforce a data range/values in a JTable Cell?

Thread view:

I have a couple of columns in a JTable where I need
to validate or enforce the following rule(s):

Col 1: 0 < n < 5 || n=="";
Col 2: 0 <= n < 1000000, max 6 digits (ie. 999999), n!="" (required).

(hope those made sense)

What is the simplest way to enforce those rules in a JTable?

TIA.

The simplest - and only - is to write a custom CellEditor with a
JTextField that filters the input, either in a custom PlainDocument
subclass, a DocumentListener, or the filter in a JFormattedTextField
(1.4 or later).
