What I have is a Container with on it a JScrollPane to hold a JTable with
data provided by a database.

The problem is that when I get the result of a query and want my new
'JTable' to replace the old one, the old one is still behind the new one.
I tried several methods like:
repaint()
validate()
upate()
or removing all with 'removeAll()' and then placing the new JTable.

The only thing that almost worked is by placing it all on a JPanel and using
the methods 'removeAll()' 'add(JTable table)' and 'updateUI()' in that
order. It didn't show the old ones anymore but my JScrollPane isn't working
either and I had to give it a size myself.

Anyone who can work this out?
