PyQt5，无法使用鼠标滚轮在显示熊猫数据帧的QTableView中滚动

from PyQt5.QtWidgets import QApplication, QTableView
from PyQt5.QtCore import Qt

table_view = QTableView()
table_view.setEditTriggers(QTableView.NoEditTriggers)  # 禁止编辑
table_view.setVerticalScrollMode(QTableView.ScrollPerPixel)  # 像素级滚动
table_view.setVerticalScrollBarPolicy(Qt.ScrollBarAlwaysOn)  # 始终显示垂直滚动条

import pandas as pd

# 假设你已经有一个名为df的熊猫数据帧
model = pandasModel(df)
table_view.setModel(model)

from PyQt5.QtCore import QAbstractTableModel, Qt

class pandasModel(QAbstractTableModel):
    def __init__(self, data):
        QAbstractTableModel.__init__(self)
        self._data = data

    def rowCount(self, parent=None):
        return len(self._data.index)

    def columnCount(self, parent=None):
        return len(self._data.columns)

    def data(self, index, role=Qt.DisplayRole):
        if index.isValid():
            if role == Qt.DisplayRole:
                return str(self._data.iloc[index.row(), index.column()])
        return None

    def headerData(self, section, orientation, role):
        if role == Qt.DisplayRole:
            if orientation == Qt.Horizontal:
                return str(self._data.columns[section])
            if orientation == Qt.Vertical:
                return str(self._data.index[section])
        return None
