如何使用pySimpleGUI将两个帧放在一起而不留间隙

import PySimpleGUI as sg

frame1_layout = [[sg.Text('Frame 1')]]
frame2_layout = [[sg.Text('Frame 2')]]

frame1 = sg.Frame('Frame 1', frame1_layout)
frame2 = sg.Frame('Frame 2', frame2_layout)

column_layout = [[frame1, frame2]]

column = sg.Column(column_layout, justification='center', element_justification='center')

window = sg.Window('Frames Example', column)

while True:
    event, values = window.read()
    if event == sg.WINDOW_CLOSED:
        break

window.close()
