A fable typically tells a story about common flaws such as pride or greed. A fairy tale features people/creatures fighting "evil" with magic or practical solutions. At the end of a fairy tale positive characters are rewarded for their good actions while negative characters are punished for their bad deeds. The moral implications can be stated by the author or readers may draw their own conclusions. In a fable the moral of the story is either told by a character or by the author. If you want good examples of fables try Aesop's Fables. I hope this helps.
