pyqt5 QStandardItemModel 复选框

Question

在pyqt5 中 QStandardItemModel 创建了一个 表格， 想在表格中加入 复选框。 全选多选 那种。 找了好多材料都没有找到 。 有没有同学碰到过这种问题呀。

用代码块功能插入代码，请勿粘贴截图

class Table(QWidget):
    def __init__(self,arg = None):
        super(Table, self).__init__(arg)
        self.setWindowTitle("QTableView表格视图控件案例")
        self.resize(500 , 300)


        sql = sql_mok.sql_mokuai()
        sql_jb = sql.huoqucanshu()

        data = sql.sql_select_pl(sql_jb["xsdd"])


        self.model = QStandardItemModel(1,1)

        self.model.setHorizontalHeaderLabels(["id","平台单号","下单日期","客户名称","总金额","手机号","收货人","收货地址","快递单号",""])


        for i,j in enumerate(data):
            # print(j)
            # tup1 = list(j)
            # tup1.append(QCheckBox())
            # j = tup1
            # j =  tuple(j)
            # print(j)

            for h,z in enumerate(j):
                item = QStandardItem(z)
                # print(i, h,z)
                self.model.setItem(i, h, item)


        # self.model.appendRow([item1, item2, item3, item4, item5])

        self.tableView = QTableView()
        self.tableView.setModel(self.model)

        frm = QFrame()
        dlgLayout = QVBoxLayout(frm)
        dlgLayout.addWidget(self.tableView)
        self.setLayout(dlgLayout)

    win.show()
    sys.exit(app.exec_())
