Shulchan Aruch
The "halachic" rulings in the "Shulchan Aruch" generally follow Sephardic law and customs, whereas Ashkenazi Jews generally follow the halachic rulings of Moses Isserles, whose glosses to the "Shulchan Aruch" note where the Sephardic and Ashkenazi customs differ. These glosses are widely referred to as the "mappah" (literally: the "tablecloth") to the "Shulchan Aruch's" "Set Table". Almost all published editions of the "Shulchan Aruch" include this gloss, and the term "Shulchan Aruch" has come to denote "both" Karo's work as well as Isserles', with Karo usually referred to as "the "mechaber"" ("author") and Isserles as "the Rema" (an acronym of Rabbi Moshe Isserles).
