Returns the formula of a cell as an RPN list of tokens that you can use to analyze it. If the cell doesn't have a formula, then this method will return null.
Note that the result is an RPN expression, so for example the formula "= 1 * 2 + 3" would be returned as "1, 2, *, 3, +". While the formula "= 1 * (2 + 3)" would be returned as "1, 2, 3, +, *"
function TXlsFile.GetFormulaTokens(const sheet: Integer; const row: Integer; const col: Integer): ITokenList; overload; override;
|const||sheet||Integer||Sheet where the formula is.|
|const||row||Integer||Row of the cell with the formula. (1 based)|
|const||col||Integer||Column of the cell with the formula. (1 based)|
