FlxConsts.Max_Columns Property
Maximum column in the spreadsheet. (0 based). Note that this number is 1 less than the maximum column count, because this value is 0-based. You can use MaxColCount to get the number of columns instead.
This number might be 255 if ExcelFile.ExcelVersion is TExcelVersion.v97_2003 or 16383 otherwise.
