TFormulaSpan.IsTopLeft Property
Indicates if this is the first formula of the array. Only the formula that is at the top left cell of the group will be used when setting a formula. Other formulas will be ignored, so you can copy formulas in a loop from one place to the other without worring if the cell is at the top left or not.
