Engineers surrender table again (8)
I believe the answer is:
resubmit
'engineers surrender table again' is the definition.
I can't judge whether this definition defines the answer.
'engineers surrender table again' is the wordplay.
'engineers' becomes 're' (Royal Engineers).
'surrender table again' becomes 'submit' (I am not sure about this - if you are sure you should believe this answer much more).
're'+'submit'='RESUBMIT'
Can you help me to learn more?
(Other definitions for resubmit that I've seen before include "Send in again" , "give in yet again" , "Put forward again" , "surrender once again" .)
