QtCore.QAbstractTableModel

QtCore.QAbstractTableModel is a class in the PyQt5 library that provides a basic framework for creating table models. This class is used as a base class for creating custom models that can be used with Qt's view classes, such as QTableView and QTreeView.

To create a custom table model, you need to subclass QAbstractTableModel and implement the following methods:

- rowCount(): returns the number of rows in the table model
- columnCount(): returns the number of columns in the table model
- data(): returns the data for a given index in the table model
- setData(): sets the data for a given index in the table model
- headerData(): returns the header data for a given section in the table model
- flags(): returns the flags for a given index in the table model

You can also implement additional methods to customize the behavior of the table model, such as sorting and filtering.

Once you have created your custom table model, you can use it with Qt's view classes to display the data in a table or tree view. To do this, you create an instance of the view class and set the model to your custom table model using the setModel() method.
