I'm using that two classes to generate a table:
(the first one uses the second)

The table is fullscreen but I'd like it to get only 90% of screen heigth and on the top of screen I'd like to put an information about f.e. internet connection etc. The problem is because I've found this Java code illegible and don't know how to move the table to the bottom for a approximately 15 px so that on the top I'd get more place for text. Could you please give me any ideas what should I change?

thank you
