qabstracttablemodel

QAbstractTableModel is an abstract base class that provides a framework for implementing table models in Qt. It provides methods for accessing and manipulating data in a table, as well as signals for notifying views of changes to the data.

Subclasses of QAbstractTableModel are responsible for implementing the following methods:

- rowCount(): Returns the number of rows in the model
- columnCount(): Returns the number of columns in the model
- data(): Returns the data at a given index in the model
- setData(): Sets the data at a given index in the model
- headerData(): Returns the header data for a given row or column
- flags(): Returns the item flags for a given index in the model

In addition to these methods, QAbstractTableModel provides signals for notifying views of changes to the data, including dataChanged(), headerDataChanged(), rowsInserted(), and rowsRemoved().

QAbstractTableModel is often used in conjunction with QTableView to provide a customizable table view for displaying and editing data.
