PySimpleGUI: How to achieve elements/frames/columns to align to the right (and resize) when resizing window

I haven't found how to achieve the following:

In the example-code, when resizing the window, the separator in the middle should go to the right, along with the changing of the window-size. The column on the left-hand - with the table in it - should resize and the table also.

What is the general procedure to do those things in PySimpleGui?

import PySimpleGUI as sg



mk = ["irgendwas"]

first_column = [
    [sg.Text("Text:")],
    [sg.Text("Content of Table")],
    [sg.Table(values=[['1','2','3','4'],['1','2','3','4']],headings=['one','two','three','four'],max_col_width=25,
                    # background_color='light blue',
                    auto_size_columns=True,
                    justification='right',
                    num_rows=20,
                    key='-UMSATZTABLE-',
                    row_height=20)],
    [sg.Button('SUBMIT', key="-SUBMIT-")],
    ]

second_column = [[
            sg.Frame(layout=[
                                [sg.Text("BText:"),  sg.InputText(size = (20,1),key="-AKT_BUCHUNGSTEXT-")],
                            ], title='actual:',element_justification='right', pad=(0,0)),
                ],
            [sg.Frame(layout=[
                                [sg.Text("Man Kat:"), sg.Combo(mk, enable_events=True, key='-MANUELLEKATEGORIEN-')],
                            ], title='Aenderung:'),
            ]
]

#col1 = sg.Col(first_column)
#col2 = sg.Col(second_column)



#layout = [[sg.Pane([col1,col2],handle_size=15, orientation='h', background_color='red', show_handle=True, visible=True, key='-PANE-', border_width=0, relief=sg.RELIEF_GROOVE)]]


layout = [
           [sg.Column(first_column),
             sg.VSeperator(pad=(0,0)),
            sg.Column(second_column),
           ]
    ]



window = sg.Window("Umbuchungen", layout,auto_size_text=True,
                   auto_size_buttons=True,resizable=True,grab_anywhere=False,border_depth=5,
                   default_element_size=(15, 1),finalize=True)


window["-UMSATZTABLE-"].expand(True,True)
window["-UMSATZTABLE-"].table_frame.pack(expand=True,fill='both')

while True:
    event, values = window.read()

    if event == "Exit" or event == sg.WIN_CLOSED:
        break
    elif event == "-MONATRET-":
        if str.isdigit(values["-MONAT-"]):
            # k.name as kategorie, substring(u.buchtext,1,45) as buchtext, u.betrag ,valuta, u.pos
            umsatzrows=ga_helper_funcs.get_monthly_revenue(db, values["-MONAT-"])
            #pos,buchtext,valuta,betrag
            positionen = [[i[4], i[1][0:10],i[3],i[2]]  for i in umsatzrows]



            window["-UMSATZTABLE-"].update(positionen)
