Failure at table to avoid row becoming audible (6)
I believe the answer is:
miscue
'failure at table' is the definition.
(bad shot in cue sports)
I cannot understand how the rest of the clue works.
(Other definitions for miscue that I've seen before include "Bad hit in snooker" , "Faulty snooker shot" , "Faulty shot on the green baize" , "Parapraxis (from a term used in billiards)" , "Strike all wrong" .)
