Determine if VisibleDropdown is True for Field in AutoFilter

[Xx7]

I would like to determine if the VisibleDrowndown is TRUE in the attached table.

The current macro sets it to FALSE in field 1. However, I want to identify when it is TRUE so I can run this macro.

Sub tester()

ActiveSheet.ListObjects("Table1").Range.AutoFilter Field:=1, visibledropdown:=False

End Sub
