How do I highlight the sorted column like the "order-column" class with Bootstrap 3?

I tried adding the "order-column" class to my table but it doesn't do anything.

One way I've got it working is to manually add the CSS for order-columns but I'm not sure if this is how it it's intended to be done.

relevant css

table.dataTable.order-column tbody tr > .sorting_1,
table.dataTable.order-column tbody tr > .sorting_2,
table.dataTable.order-column tbody tr > .sorting_3 {
background-color: #f9f9f9;
}
