I had my Shabbos meal on the floor once. We had just moved into the apartment and we didn’t have a table and chairs yet.
Anyway most of us daven Shemoneh Esrei before we eat, so it would be the davening leading up to the kneidlach.
Which I can understand being as kniedlach might be a mitzvos asei midoraisa of oneg and kavod Shabbos while davening is a mitzvah d’rabonnon as a zecher for the korbannos.
