如何在QTableWidget中获取单元格的索引？

# 导入必要的模块
from PyQt5.QtWidgets import QApplication, QTableWidget, QTableWidgetItem
import sys

# 创建应用程序对象
app = QApplication(sys.argv)

# 创建QTableWidget对象
tableWidget = QTableWidget()

# 设置表格的行数和列数
tableWidget.setRowCount(3)
tableWidget.setColumnCount(3)

# 填充表格数据
for row in range(3):
    for col in range(3):
        item = QTableWidgetItem(f"Row {row}, Col {col}")
        tableWidget.setItem(row, col, item)

# 获取当前选中单元格的索引
currentRow = tableWidget.currentRow()
currentColumn = tableWidget.currentColumn()

# 获取选中单元格的QTableWidgetItem对象
selectedItem = tableWidget.item(currentRow, currentColumn)

# 获取选中单元格的行和列索引
selectedRow = tableWidget.row(selectedItem)
selectedColumn = tableWidget.column(selectedItem)

# 打印结果
print(f"选中单元格的索引：({selectedRow}, {selectedColumn})")

# 运行应用程序
sys.exit(app.exec_())
