jtable column validation

hi,

I have to display a alert message while entering the value in the column based on the previous column and return focus to the same column. How can I do this. I am new to JTable.

Thanks in advance.
Regards,
Deepthi.

Hi Deepthi!

What have you tried so far? And how where you thinking of displaying that alert? (e.g. a separate window, a textfield, in a different cell of the JTable...)

Greetings,
Nepomuk
