When you are doing the sort under 'data'...'sort'....'options' see if the
sort left to right is checked off rather than sort top to bottom.

Have a plain table of whole integers, nothing unusual. This is a new PC. If I
try to sort on a column, no sort is performed. (The order might remain as
693, 166, 9968, for example). Nothing is locked nor protected. I have never
had this problem before. This spreadsheet sorted ok on my old PC. What is
wrong?
