Trying to add 10 values to sql database
===

This is easy enough task under sql management studio. I clicked on edit top 200 rows. And entered first set of values as:

Everything should be same except Index and rollnumber

    Index class rollnumber age 
    1      A      1         10
    2      A      2         10
    3      A      3         10
    ...
    10     A      10        10

Problem i am having is:
I copied first row and pasted in second row and when i try to change it in sql editor i am unable to. 
Can anyone please tell me what is the best way to do this through sql editor?

Or if there is easier way to do SQL insert in this case?
