使用pyqt5显示选定行中的一个单元格

import sys
from PyQt5.QtWidgets import QApplication, QMainWindow, QTableView, QHeaderView
from PyQt5.QtGui import QStandardItemModel, QStandardItem

def display_selected_cell(row, column):
    selected_cell = table_model.item(row, column)
    print(selected_cell.text())

app = QApplication(sys.argv)
window = QMainWindow()
window.setGeometry(100, 100, 500, 500)

# 创建一个数据模型
table_model = QStandardItemModel(4, 3)
table_model.setHorizontalHeaderLabels(["Column 1", "Column 2", "Column 3"])

# 添加数据到单元格
for row in range(4):
    for column in range(3):
        item = QStandardItem(f"Row {row}, Column {column}")
        table_model.setItem(row, column, item)

# 创建一个表格视图
table_view = QTableView()
table_view.setModel(table_model)
table_view.horizontalHeader().setSectionResizeMode(QHeaderView.Stretch)

# 将信号连接到槽函数
table_view.clicked.connect(display_selected_cell)

window.setCentralWidget(table_view)
window.show()

sys.exit(app.exec_())
