I am trying to create a scroll bar in the window but facing some challenges. Kindly assist me in correcting the codes where necessary.

class registerTB(QMainWindow):
    def __init__(self):
        super().__init__()
        self.setWindowTitle("CREATE ACCOUNT")
        self.setGeometry(100,100,1500,1000)

        self.centralwidget = QWidget(self)
        self.gridLayout = QGridLayout(self.centralwidget)
        self.scrollArea = QScrollArea(self.centralwidget)
        self.scrollArea.setWidgetResizable(True)
        self.scrollAreaWidgetContents = QWidget()
        self.scrollAreaWidgetContents.setGeometry(QtCore.QRect(0, 0, 379, 207))
        self.verticalLayout = QVBoxLayout(self.scrollAreaWidgetContents)
        self.tableWidget = QTableWidget(self.scrollAreaWidgetContents)

        self.verticalLayout.addWidget(self.tableWidget)
        self.scrollArea.setWidget(self.scrollAreaWidgetContents)
        self.gridLayout.addWidget(self.scrollArea, 0, 0, 1, 1)
        self.setCentralWidget(self.scrollArea)  #I can also set this to setcentralwidget(self.centralwidget) so I can still use self.scrollArea

        self.scrollArea.setVerticalScrollBarPolicy(Qt.ScrollBarAlwaysOn)
        self.scrollArea.setHorizontalScrollBarPolicy(Qt.ScrollBarAlwaysOn)
