放置分页表格控件的容器

class Example_widget(QtWidgets.QWidget):
    def __init__(self):
        super().__init__()
        self.init_ui()
        pass
    def init_ui(self):
        self.setWindowTitle('表格显示示例')
        self.table = PageTableWidget()
        self.table.sinout_signal.connect(self.table_signal_recive)
        layout = QtWidgets.QVBoxLayout()
        layout.addWidget(self.table)
        self.setLayout(layout)
        pass
    def setting_data(self,data1,data2):
        self.table.set_table_init_data(data1)
        self.table.set_table_full_data(data2)
        pass
    def table_signal_recive(self,data:Dict[str,Any]):
        print(data)
        pass

使用

if __name__ == '__main__':
    app = QtWidgets.QApplication(sys.argv)

    pre_data = {}
    pre_data['headers'] = ['编号','姓名','性别','归属']
    pre_data['table_right_menus'] = {
        '右菜1':'target_11',
        '右菜2':'target_22',
        '右菜3':'target_33'
    }

    pre_body_data = [
        ['000','林黛玉','女','红楼梦'],
        ['001','孙尚香','女','三国演义'],
        ['002','孙悟空','男','西游记'],
        ['003','刘备','男','三国演义'],
        ['004','宋江','男','水浒传'],
        ['005','贾宝玉','男','红楼梦'],
        ['006','关羽','男','三国演义'],
        ['007','张飞','男','三国演义']
    ]

    t_win = Example_widget()
    t_win.setting_data(pre_data,pre_body_data)
    t_win.show()
    sys.exit(app.exec_())
    pass

右键选择菜单点击后，该行的内容会回传到容器控件

控制台输出了容器中接收到的信息

{'action_name': '右菜1', 'action_target': 'target_11', 'action_data': ['002', '孙悟空', '男', '西游记']}
