The screen shot you included is not a value table.  I believe that Name, Operator, Type, Value, and Combine Using are all separate parameters for the tool and they have been given "Condition Barriers" as their category value.  Categorized parameters show up in drop-down groups like that.  Last I remember, categories are collapsed by default.
