Well, all cbind does in that context is to remove the embellishments
of the ftable structure, exposing the N x 2 internal matrix. Various
other matrix operations, including indexing, has the same effect, e.g.

data(Titanic)
ftable(Titanic, row.vars = 1:3)[,]    # same as using cbind()
ftable(Titanic, row.vars = 1:3)[,2:1] # what you want
