First of all use a proper image description...

To your question: You can see the answer in your picture. You just have to edit the tablemodel (right side at the bottom). There you can insert a new row or a new column and put some test data into the table.

If you want to learn swing I wouldn't recommend to start with the GUI designer. Yes it's a very useful tool and probably the best GUI designer for Java atm but the downside is that you don´t learn the basics of swing with that.

I would recommend to create some JFrames first via coding them by yourself and by recreating some good examples like this one: https://examples.javacodegeeks.com/desktop-java/swing/jframe/java-jframe-example/ or this: https://docs.oracle.com/javase/tutorial/uiswing/learn/index.html
