Several tables in the LMS can be sorted by clicking on the title of the desired column. E.g. you can sort the students in a group by last name, by clicking on the word 'last name ' at the top of the table. When you click 'last name' once more, the sorting order is reversed. Some tables cannot be sorted. The order of the rows in these tables has a special meaning. Often these rows can be dragged (with the left mouse button) within the table to alter their order.
