Java: Adding Row in JTable
1 Answer(s)      3 years and 6 months ago
Posted in : Java Beginners


how about if we already have the JTAble created earlier.

And i just found nothing to get its DefaultTableModel, thus, I can't call insertRow() method.

Is there any work around for this?

I found that we need to re-create the table as a whole using AbstractModel, (what??)

(--__--)" uh oh....
