One's nailed to end of table (3)
I believe the answer is:
toe
'one's nailed' is the definition.
(I've seen this before)
'to end of table' is the wordplay.
'end of' says to take the final letters.
The final letter of 'table' is 'e'.
'to'+'e'='TOE'
(Other definitions for toe that I've seen before include "Part of foot" , "One with sock on" , "Pedal digit" , "Front of shoe" , "Lower end or tip" .)
