how to add a serial number column in a view? I created a view in drupal and needs some serial numbering as the first column which is not there in the content type on which I created the view. My question is how to add that serial number field in this view like this

cand_name | phone_num | email id


is my view

I want it like this..

sno | cand_name | phone_num | email id


hope I am clear, write comments if it needs still clear explanation.

Thanks in advance
You should use Global: view result counter field defined in a view.

OR if you want a serial field for the content type you can use 

the module serial field
