Sort Excel 2010 Table by Headers

By the way, in case you think that I didn't at least try and hit ok:

In the drop down menu where it says CompactLogix for the table sorting, it simply gives me the options between all of my different table headers. This sorts each column in accordance with the sorting variability of that specific header that I choose.
What I'd actually like to do is sort all of my headers in alphabetical order form left to right. Now, of course I could simply cut and paste each header manually, but I have nearly 50 headers and that would be quite the time consuming task, especially considering Excel should be able to do this for me!

Keep in mind: this does work if I convert my table to a range, but why should I have to do that? Shouldn't I be able to sort my table as if it were any other set matrix?
