我正在创建一个频率表计算器。我想移动一个添加到布局中的表格小部件。现在我已经在 qwidget 中设置了布局并显示了它。当我尝试使用 qwidget 移动布局时。它给了我错误。move(self, int, int): argument 1 has unexpected type 'QVBoxLayout'

我知道 QVBoxLayout 不能独立移动。所以我尝试将 QVBoxLayout 嵌入到 QWidget 中，但它仍然不起作用。

from statistics import mode
import sys
from functools import cached_property
from PyQt5 import QtWidgets
from PyQt5 import QtCore
from PyQt5.QtWidgets import QLabel, QWidgetItem
from PyQt5.QtCore import QObject, pyqtSignal
from PyQt5.QtWidgets import QPushButton, QApplication, QTableWidget, QTableWidgetItem, QVBoxLayout, QWidget
from pynput.keyboard import Listener, KeyCode

a = KeyCode(char="a")

def getSelectedItemData():
    for currentItem in tableWidget.selectedItems():
        print(f"ROw : {currentItem.row()} Column : {currentItem.column()} {currentItem.text()}")


app = QApplication(sys.argv)

qwidget = QWidget()

qwidget.setWindowTitle("Python GUI Table")
qwidget.resize(412,597)

layout = QVBoxLayout()

tableWidget = QTableWidget()
tableWidget.setColumnCount(2)
tableWidget.setRowCount(0)

# adding item in table
tableWidget.setHorizontalHeaderItem(0, QTableWidgetItem("Scores"))
tableWidget.setHorizontalHeaderItem(1, QTableWidgetItem("Frquency"))
tableWidget.setHorizontalHeaderItem(2, QTableWidgetItem("FX"))
tableWidget.setItem(0, 0, QTableWidgetItem(""))
tableWidget.setItem(0, 1, QTableWidgetItem(""))
tableWidget.setItem(0, 2, QTableWidgetItem(""))

tableWidget.setItem(1, 0, QTableWidgetItem(""))
tableWidget.setItem(1, 1, QTableWidgetItem(""))
tableWidget.setItem(1, 2, QTableWidgetItem(""))

tableWidget.setItem(2, 0, QTableWidgetItem(""))
tableWidget.setItem(2, 1, QTableWidgetItem(""))
tableWidget.setItem(2, 2, QTableWidgetItem(""))

tableWidget.setItem(3, 0, QTableWidgetItem(""))
tableWidget.setItem(3, 1, QTableWidgetItem(""))
tableWidget.setItem(3, 2, QTableWidgetItem(""))

#formating table
header=tableWidget.horizontalHeader()       
header.setSectionResizeMode(0, QtWidgets.QHeaderView.Stretch)
header.setSectionResizeMode(1, QtWidgets.QHeaderView.Stretch)

#initialzing table
tableWidget.doubleClicked.connect(getSelectedItemData)
layout.addWidget(tableWidget)
qwidget.move(layout, 200, 400)
qwidget.show()

为什么布局很重要

# Adding Row Button

        tableWidget.insertRow(tableWidget.rowCount())


key_listener = KeyListener()
key_listener.pressed.connect(handle_pressed)
