Remains in rows (6)
I believe the answer is:
scraps
I believe this is a double definition.
'remains' is the first definition.
(thesaurus)
'rows' is the second definition.
(I've seen this in another clue)
'in' acts as a link.
(Other definitions for scraps that I've seen before include "bits left over?" , "Fragments for fights" , "Abandons as unworkable" , "Small fragments" , "Oddments - fights" .)
