It isn't entirely clear to me what you want.
table() can function with many kinds of data, not just integers, so it
returns a vector with names.
For your case, with integer classes, you seem to possibly want:
> x <- table(k)
> x <- rbind(as.numeric(names(x)), as.numeric(x))
> x
[,1] [,2] [,3] [,4] [,5] [,6]
[1,] 1 2 3 5 6 9
[2,] 9 2 3 1 1 1
but a more general approach is:
> x <- table(k)
> x[1]
1
9
> names(x[1])
[1] "1"
> as.numeric(names(x[1]))
[1] 1
