Advanced component does not mean how "advanced" the component is, but means powerful. If you want to realize a fully functional table function, it may take several days to write a lot of code. You can call the wx.Grid component directly and do it in three or two times, so this component is very advanced.

Common advanced components of PyQt5 include table view control QTableView, QTableWidget and list view QList

View and QListWidget, tree structure QTreeWidget and label view QTabWidget.

The table view control QTableView needs to be used with the data model. The data model of the table needs to fill in the data of each row and column, just like the execl table.

QTableView is designed based on MVC mode. M(Model) is the data model, V(view) is the QTableView View, which is used to display the data model, and C (controller) is the controller, which is combined with View. Bind the data source through the setModel() method. The common methods are as follows:

The model data that the table view control QTableView can bind is shown in the following table:

The common methods of the model are shown in the table below:
