Sort by should support an array of values

Create an S- or M-sized course (to generate users with similar names) Open course page => Participants Take note on how the users are sorted by Surname in ascending order default Try applying various combinations of sort orders. Take note of the columns which you applied sorting on. Confirm that each sort order has the correct effect (i.e. ascending and descending) Confirm that the users are sorted based on the latest sort column you applied sorting on down to the last applied column sorting. For example: You sorted the users by email into descending order, then you should see the users sorted by email in descending order. Then you sorted the users by the first name in ascending order, then you should see the users primarily sorted by their first name in ascending order. Then users with the same first name will be sorted based on their emails in descending order. Reset the table preferences. Confirm that the users are sorted by the default sort. Confirm that the " Reset table preferences " link disappears.
