TableView is very widely used in IOS apps. TableView can also be very rich in content and diversity. Therefore, the performance optimization of TableView is very important to the user experience of our app. First, UITableView uses the Multiplexing cell mechanism for performance optimization. The basis of Tableviewcell's multiplexing mechanism is to set the Tablev

First, add a table header: Qstandarditemmodel *model = new Qstandarditemmodel (); Model->setcolumncount (2); Model->setheaderdata (0,qt::horizontal,qstring::fromlocal8bit ("card number")); Model->setheaderdata (1,qt::horizontal,qstring::fromlocal8bit ("name")); Second, set the table properties: Ui->tableview->setmodel (model); Table header information shows left Ui->tableview->horizontalheader ()->setdefaul
