Displaying column data

I have a stored proc that brings back data like this:
Id, Name, Code, Quantity
1    x          c1        2
2    y         c2         5
3    z          c1        10

I want to have it like this: basically, i want to have "Code" as the column header with "quantity" under it. I dont want to have a olumn for code and a column for corresponding quantity. Doable??

id, Name, c1,  c2,
1   x         2      0
2   y         0      5
3  z          10    0
