Work found in writing table (7)
I believe the answer is:
propose
'table' is the definition.
(I've seen this before)
'work found in writing' is the wordplay.
'work' becomes 'op' (abbreviation for opus).
'found in' indicates putting letters inside.
'writing' becomes 'prose' (I've seen this in other clues).
'op' put into 'prose' is 'PROPOSE'.
(Other definitions for propose that I've seen before include "advance" , "Put forward for consideration" , "Make an offer of marriage" , "Put forward a plan" , "Offer for consideration" .)
