Returnerar the classic XLS AutoFilter field collection for the worksheet. Read-only
Samlingen använder 1-baserade fältindex som motsvarar de synliga AutoFilter-kolumnerna. Count returns the number of filtered columns in the current range. Items[Field] and Find(Field) return a TXLSAutofilterItem for that field or nil when the field index is outside the current range
Each item exposes Active, Operator, Criteria1, and Criteria2. Criteria objects expose the stored BIFF8 DOPER DataType, grbitSgn, and Value
