pyqt5我想知道如何在qtableview中选择行值

from PyQt5.QtWidgets import QApplication, QMainWindow, QTableView, QAbstractItemView
from PyQt5.QtGui import QStandardItemModel
from PyQt5.QtCore import Qt

app = QApplication([])
window = QMainWindow()

table_view = QTableView()
table_view.setSelectionBehavior(QAbstractItemView.SelectRows)  # 设置选择行为为选择整行
table_view.setSelectionMode(QAbstractItemView.SingleSelection)  # 设置选择模式为单选

model = QStandardItemModel()
model.setHorizontalHeaderLabels(["列1", "列2", "列3"])  # 设置表头

# 添加数据
data = [
    ["数据1", "数据2", "数据3"],
    ["数据4", "数据5", "数据6"],
    ["数据7", "数据8", "数据9"]
]
for row, row_data in enumerate(data):
    for column, value in enumerate(row_data):
        item = QStandardItem(value)
        model.setItem(row, column, item)

table_view.setModel(model)  # 设置模型

def handle_selection_changed(selected):
    if selected.indexes():
        row = selected.indexes()[0].row()  # 获取选中行的索引
        values = [model.item(row, column).text() for column in range(model.columnCount())]  # 获取选中行的值
        print("选中行的值：", values)

table_view.selectionModel().selectionChanged.connect(handle_selection_changed)  # 连接选择变化信号与槽函数

window.setCentralWidget(table_view)
window.show()
app.exec_()
