Typically, the lists are records in a collection that is to be sorted.
Records... { "a1", "b1", "c1" } { "a1", "b1", "c2" } { "a1", "b2", "c1" } { "a1", "b2", "c2" } { "a2", "b1", "c1" } { "a2", "b1", "c2" } { "a2", "b2", "c1" } { "a2", "b2", "c2" } Records sorted in ascending order on columns 0, 2... { "a1", "b1", "c1" } { "a1", "b2", "c1" } { "a1", "b2", "c2" } { "a1", "b1", "c2" } { "a2", "b1", "c1" } { "a2", "b2", "c1" } { "a2", "b1", "c2" } { "a2", "b2", "c2" }
