Crack in captain's table (4)

I believe the answer is:

stab

'crack' is the definition.
(thesaurus)

'in captain's table' is the wordplay.
'in' says the answer is hidden in the clue.
'STAB' can be found hidden inside 'captains table'.

(Other definitions for stab that I've seen before include "Wound with pointed weapon" , "Rough guess; to knife" , "Attack with a dagger" , "Go" , "effort" .)

I've seen this clue in The Telegraph.
