JTable get Old Value in the Listener of change Value

843805Jan 19 2006 — edited Jan 21 2006

Software
--------------
JDK 1.5 Update 6

Requirements
-----------------------
I have a JTable I want to show the sum total of certain Cell Value.So I have added a TableModelListener by which on updating the cell Value I change the total in the JTextField. The Problem is If I change the value then I have to get the previous value that the cell had. How to get that original value before the update.

There is a way by which we can get the same by inserting one dummy column which stores previous value.But this method inserts unneccessary if you require the total of 3 columns and if you require the same thing again and again in different frames

Is There any way by which we can show the total

Thanks in advance
