'Euer' is the genetiv form of 'ihr'. So in this meaning, it is a correct answer of 'your table'. But most of time, 'euer' is writen in 'euerer'.
I think that whether it's "euer" or "eure" depends on the gender of the noun. ihr (plural you" uses "euer/eure" Right, we haven't really been taught "eure/euer". Anyway, here's a sentence from a previous lesson I've done: "Die Katze trinkt eure Milch" which means "The cat drinks your milk." It's "die Milch". "Das ist euer Hund." is another sentence. "That is your dog." "der Hund".
