Hi,
Please use code formatting when you post code. See the formattings tips:

I can't see that you have added your table or scroll pane to any content pane. That's why it isn't displayed.

Ps.
You have lots of assignements of Strings when you are declaring your variables, it's useless, just set them to null.
