There should be a pipe character (|), not a comma, between  and the column name. And you have to do it separately for each column that you want to be unsortable. Like this:

class="unsortable" does not remove the table's other classes, so you don't have to set those again on the unsortable columns. You only have to specify the things that you want added or changed, such as column alignment.
