Hi im still relatively new to python and i am designing a multiplication table that enables a user to input the size of the times table unfortunately ive stumbled on the nested loops this is what i have right now:

a=raw_input('please enter a number')
b=int(a)
n=b+1
for row in range(1, n):
     for col in range(1, n):
             print "%3d " % (row * col),
     print

the input which comes out is:
  1    2    3    4    5 
  2    4    6    8   10 
  3    6    9   12   15 
  4    8   12   16   20 
  5   10   15   20   25

however i need something more on the lines of:
| 2 3 4 5
==================
2 | 4 6 8 10
3 | 6 9 12 15
4 | 8 12 16 20
5 | 10 15 20 25

does anyone know what i need the third nested for loop to be ? to make it like the above example. Pleasee help me !!
