This is easy to do - just click the column header (i.e., First Name, Last Name, etc.) to sort the records for the field that you click. Click once and the records are sorted from A-Z. Click again and they are sorted from Z-A.
By the way, in your attached graphic file, it shows last names in the First Name field, and first names in the Last Name field. Is it that way in the actual DB, or is your screenshot just a test DB?
