==Secondary sortkey==

==Secondary sortkey==

If a column contains a value multiple times then sorting the column preserves the order of the rows within each subset that has the same value in that column ({{mlw|Sorting_algorithm|Stability|stable sorting}}). Thus sorting based on a primary, secondary, tertiary, etc. sortkey can be done by sorting the least-significant sortkey first, etc.
