Pascal's triangle

In mathematics, Pascal's triangle is a geometric arrangement of the binomial coefficients in a triangle.

          1
        1   1
      1   2   1
    1   3   3   1
  1   4   6   4   1
1   5  10  10   5   1

The task

Write an APL function that takes argument and return a triangle like the one shown above. The argument defines the number of layers. The shown example has 6 layers, for example.

In APL, of course this can be done in a single line of APL.
