Does this mean you want to sort 9 columns based on just that one "year" column?
If yes, just select your range (include all 9 columns), then data|sort. Follow
the dialog from there--just specify the first field and ascending or descending.
If you mean you want to have 9 levels of sort, then since xl only allows 3
fields per data|sort, you can sort by the 3 most minor, then sort by the 3
middle, then sort by the 3 major fields.
That'll be 3 different data|sorts.
