True if the AutoFilter drop-down arrows are visible. Read/write Boolean.
Remarks
This property returns True if the AutoFilter drop-down arrows are currently displayed. You can set this property to False to hide the arrows, but you cannot set it to True. Use the AutoFilter method to filter a list and display the drop-down arrows.
If the Auto Filter drop-down arrows are visible but no rows are currently filtered (all rows are visible), the AutoFilterMode property is True and the FilterMode property is False.
