Offset Dynamic Named Range

I know how to create a dynamic named range so that no blanks appear in my data validation list but have only ever done this for a list in a column, i.e...

-----A-----
1--Apple
2--Orange
3--Pear
4--Bannana
5--
6--

A1:A6 would be named Fruit, then name manager, edit: =OFFSET($A$1,0,0,COUNT($A1:$A6),1)

The Data Validation list then shows Apple, Orange, Pear, Bannana. And if I add Peach into A5 later, that then appears in the list.

What I need though is to edit this as if the named range 'Fruit' covers cells A1:F1.

------A---------B-------C--------D-----------E-----------F
1--Apple---Orange---Pear---Bannana---
2--
