Discussion
New cells are created if needed with makeCell(atRow:column:). This method redraws the receiver. Your code may need to send sizeToCells() after sending this method to resize the receiver to fit the newly added cells.
If the number of rows or columns in the receiver has been changed with renewRows(_:columns:), then new cells are created only if they’re needed. This fact allows you to grow and shrink an NSMatrix without repeatedly creating and freeing the cells.
