My Problem is.
I have a JTable with 2 columns ( Rows can be 1-10 depending upon the size of
input vector)
I have provided two button in my Frame
1)Update Row
2) Update whole Table.
Now i want I want that if a user makes a change in any cell say cell( row
3,Col 1) ;and moves to next row , then the color (background/foreground) of
that cell should change to any other color .Again if he presses any of the
button then the default color of the cell should be restored.Basically i
want to indicate the user that he has made changes in the cell and he needs
to press the button for updation
Now i have wriiten code as

but the problem is that when i click the button the background of cell is not changed from red to
blue. In the action lperformed events of button i have made edited as false.

Just a thought, but since the object is to alert the user to changes. Why not just start with the update button not enabled and when any cell is changed enable it?
I agree. Here's the link:
