Sort Data Alphabetically without using a Macro

Hello,

I am working on a document for a co-worker who isn't very tech-savvy. I have a two-column list on the third worksheet of the attached workbook. I would like to figure out a way to sort this list by clicking a button located in a cell (somewhere around D10). However, I want to avoid macros if at all possible. If not, what other ways are there to make it easy for a non-tech-savvy person to sort the list without using a macro?

Thank you.
