I have an array :

a =
[ [10, 11], [20, 21],
  [12, 13], [22, 23],
  [30, 31], [40, 41], 
  [32, 33], [42, 43] ]

I want to know how to manipulate the array to get :
a.grid(1)
==> [10, 11], [12, 13]
A.grid(2)
==> [20, 21], [22, 23]
A.grid(3)
==> [30, 31], [32, 33]
A.grid(4)
==> [40, 41], [42, 43]

B = a.grid(1)
==> [10, 11], [12, 13]
B[1][1]
==> 10
B[2][2]
==> 13

A.row(1)
==> [10, 11, 20, 21]

A.col(1)
==> [10, 12, 30, 32]


Many many thanks for your examples.
