Can't resize containers in scrollArea

[paparucino]

Hello, I'm new to the list and besides apologizing for any errors please 
correct me so I can improve.
My problem is that I can't delete the white space after the table with 
the data. Pls look at the attached drawing.
The script I use is the one below.
I noticed that whatever the value used for the various sizes (apart from 
MainWindow.resize (900, 650)) none of them affect the size of both the 
internal table and its container. I guess they are default values and I 
am not able to change them.
Any help is appreciated.
