Striking reason to eat from one's lap? (7)

I believe the answer is:

notable

I'm a little stuck... Click here to teach me more about this clue!

'striking' is the definition.
(I've seen this before)

I can't explain the rest of the clue.

(Other definitions for notable that I've seen before include "Widely known and esteemed" , "Striking" , "Impressive" , "Worthy of record" , "well known" .)

I've seen this clue in The Sun.
