TypeError: 'Table' object is not callable

[Melford]

Oh god, that looks horrible, I was hoping it'd looking more like this:



I'm assuming it might have something to do with:

list1 = Listbox(window, height=35, width=35)

Is there any reason the boxes aren't stacking like the screenshot as I'm using it as a reference as its simple but something I (thought) could grasp? I think I might've miss tagged something so the boxes appear blank next to name?
