I have a Google spreadsheet with two tabs:
First one is a public one where I want to invite specific customers to edit it.
Second one is just for my team and I would like it to be invisible to the customers.
In new (May 2014) Google Sheets I am not able to do it.
In a few words: On a Google Sheets with two tabs how to let some users edit only first tab and not show them the second, while keeping the full spreadsheet editable for another group of users?
