I put a header in A1, and wrote numbers in A2:A7. I highlighted A1:A7, clicked on Data, Sort, Sort, saw my header in the top slot ("Sort by"), made sure the option "Header row" under "My list has" was selected, said OK, and, the sort took place on A2:A7 only. My header remained in A1.
Same as above, except I highlighted only A2:A7. And, I just hit the A/Z icon in the Standard toolbar. A2:A7 only was sorted.
