Как правильно заполнить ячейки QTableWidget данными QDateTimeEdit

В этом коде в таблице TableWidget в первый столбец вставляется dataEdit, но почему при запуске кода открывается таблица но, без dataEdit.

Как это исправить?

test_ui_log.py

import sys
from PySide2.QtCore import *
from PySide2.QtGui import *
from PySide2.QtWidgets import *
from test_ui import Ui_MainWindow
from PyQt5.QtCore import *
from PyQt5 import QtWidgets
from PyQt5 import QtCore


app = QApplication(sys.argv)

Window = QMainWindow()
ui = Ui_MainWindow()
ui.setupUi(Window)
Window.setFixedSize(320, 240)
Window.show()

def dataEdit():
    pass



row = 3
column = 2
ui.tableWidget = QtWidgets.QTableWidget(row, column)

for row in range(ui.tableWidget.rowCount()):
    date_from = QtWidgets.QDateTimeEdit()
    date_from.setDateTime(
        #QDateTime(QDate(2021, 9, 4))
        QtCore.QDateTime(QtCore.QDate(2021, 8, 26), QtCore.QTime(15, 0, 0))
    )
    ui.tableWidget.setCellWidget(row, 0, date_from)  # !!!

sys.exit(app.exec_())

Вот .ui: test_ui.py
