如何在QTableWidget中获取ButtonWidget的行？

from PyQt5.QtWidgets import QApplication, QTableWidget, QTableWidgetItem, QPushButton

app = QApplication([])

tableWidget = QTableWidget()
tableWidget.setRowCount(3)
tableWidget.setColumnCount(2)

# 添加ButtonWidget到表格中
button = QPushButton("Button")
tableWidget.setCellWidget(1, 0, button)

# 遍历表格的所有行
for row in range(tableWidget.rowCount()):
    # 获取每一行的单元格
    cellWidget = tableWidget.cellWidget(row, 0)
    # 判断单元格中的控件是否为ButtonWidget
    if isinstance(cellWidget, QPushButton):
        # 获取ButtonWidget所在的行
        buttonRow = tableWidget.indexAt(cellWidget.pos()).row()
        print("ButtonWidget所在的行：", buttonRow)

app.exec_()
