I have a sentence
There isn’t ------ egg on the table.
Should the gap have any or an? What's the difference?

I'm sorry Stockfish decided to pull his inspiring answer.
You may or may not expect many assorted eggs on the table. You may have been told that the table is where the egg was placed. Saying "There is not an egg" would be fine. If you had expected to find more than one egg then saying an egg would be a good way to emphasize your surprise. As would saying "There is not a single egg on that table".
If you were told that the table was covered in cooked/fried/scrambled etc. eggs then finding a clean table you could say "There isn't any egg on this table." Looking for a related food stain on your shirt you might say "There isn't any egg on my shirt".
"Egg" may be found as the singular in the shell or in the plural as the processed meal. As such it is not the best word to explore the a versus an question.
