Lock information in rows, but allow sorting and filtering

I have a spreadsheet with an employee's name, date of birth, company and salary.
The information in rows should never change (or be able to be changed); although, another person in my office needs to view the information in the spreadsheet. He will need to sort the information different ways (by company, or by salary). So I want that person to be able to sort and filter without editing any information, or having any of my information in the rows change. Possible?

When I follow those directions - it still comes up with the warning that says the chart is protected and read only, and I'm still not able to edit. I'm not sure there is a way to do what I'm trying to accomplish.
