Add a class to sortable columns th

[waiting-for-dev]

I think a class should be automatically added (or even better, added if configured) to the th of the columns that can be sorted. That way there would be an easy way to take that columns and add some CSS to them (for example, a draggable cursor).

Thanks a lot for this plugin!

[DataTables]

DataTables adds one of sorting_asc, sorting_desc or sorting (sortable but no sorting applied) to the cells which are sortable. So you could add:

.sorting_asc,
.sorting_desc,
.sorting {
   cursor: move;
}

to your CSS.
