Allowing entry only in specific rows or columns

Allowing entry only in specific rows or columns

Hello,
I am trying to use Zoho in my huge organisation and hope to implement in for more than 30000 users. Before I do that I have a very important issue to be resolved.

I want to share sheet to all, but allow adding/editing of content to only specific rows/columns. This way shared users can see the content of whole document, but can add only his row/column.

Can you help me do this?

Regards,
Kushal
