Butter, jam, or marmalade and many other things on the table (6)
I believe the answer is:
spread
I believe this is a double definition.
'butter jam or marmalade' is the first definition.
(butter, jam and marmalade are types of spread)
'many other things on the table' is the second definition.
(spread can mean a food selection)
'and' is the link.
(Other definitions for spread that I've seen before include "expansion?" , "See 4" , "Sort of betting" , "Courses" , "Scatter - padres (anag)" .)
