I am giving answer to my question .. Actually I tried and found one solution from the following link:

From odoo forum

There are some issue which I found in that answer but didn't able to solve that :(

Issues are:

(1) I make change in base model of web in that "view_list_editable.js" as told in this link insted of my custom model.

(2) Also when any read-only fields is there in between One2Many visible fields then this solution is not working..
