Interface CellChangeIf<T>

One changed cell: row, column, old and new value – the unit of a change set (GeModelChangeEvent.changes, TableApi.getPendingChanges). With old and new value it is enough for undo and redo.

Example

const listener = new EventAdapter();
listener.onModelChanged = (evt: GeModelChangeEvent) => {
  for (const change of evt.changes ?? []) {
    console.log(change.property, change.oldValue, "→", change.newValue, change.row);
  }
};
