The reason I do not want to use the code exactly on this link is it creates a new window and doesn't use the form that I already am using. The pre-existing form has jPanel1 (swing JPanel) containing jPanel3 (swing JPanel). And, jPanel3 contains jTable1 (swing JTable).

I don't think you want to be doing this. 
I presume the jTable1 already exists, and has a parent.

Nowhere that I can see are you setting the new table model in jTable1.

The code below works. It's just a basic JFrame app. created in NetBeans, with the code 
inserted to set the model/sorter for the default table. If you don't change the model
the code will throw OOB exception because the model data in the sorter only has 3 columns,
and the default table created by Matisse has 4.
