    Parent of this GUI is the MainWindow.
    
    Handles the GUI of the table. The table is given to is a parameter when
    updating the table so this class knows nothing of the game. First I had
    the scaling of the TableGUI when the window is resized, but since my original
    plan didn't work, I'm not using it anymore.
