Good thought in regards to the table, but they are reclining at the table during the scene of the Last Supper.
Just bought the coffee table edition of The Passion of The Christ, and it clearly shows the disciples sitting on the floor around the table. (Actually there are 3 tables in this scene! {page 104-105})
I picked up a book on the literature of Christ (1946 copyright) at our local library, and in it are many poems and stories speaking of Jesus's life. During the passion, one writer, Mary Borden writes a tale titled, From Friday to Sunday. In the story she has Mary Magdalene waving a robe to keep the birds from scavenging at Christ on the cross.
