WebTable works the same way JTable does, meaning you can read about JTable and apply that knowledge to WebTable in your application. The only difference between JTable and WebTable are some additional useful methods in WebTable which may be handy in case you know how to work with JTable.
Unfortunately I cannot help you to learn Swing basics, but I can point you to proper articles/examples.
I suggest you to read official JTable tutorial:http://docs.oracle.com/javase/tutorial/ ... table.html
That will give you a general idea of how JTable content is displayed.
You may find other useful tutorials there as well.
