Seems like a Swing question to me. Or maybe an ordinary Java question -- "How do I save data from a Java program?" Doesn't belong here, anyway, let's move it.

One part of the answer is that you would save the data from the table model, which is where the data is stored. Don't consider saving the JTable, that's just a GUI component used to display the data. Okay, that takes care of the Swing part of the question, the rest is just Java programming. Moving...
