Hi,

A quote from QAbstractTableModel docs:

Models that provide interfaces to resizable data structures can provide
implementations of insertRows(), removeRows(), insertColumns(), and
removeColumns(). When implementing these functions, it is important to call
the appropriate functions so that all connected views are aware of any
changes:
- An insertRows() implementation must call beginInsertRows() before
inserting new rows into the data structure, and it must call endInsertRows()
immediately afterwards.
