Part of my code:

function listaProjetos(){
  $('#datatable').DataTable({
        ///////////////     
        "columnDefs": [
            { "orderData": 1, "targets": 0 },
            { "orderData": [2, 1], "targets": 1 },
        ],      
        ///////////////

Basically, I need to change the column AÇÃO, to remove the arrows, and remove the function where clicking on the name will will sort the table.

However, I can't use the function:

{ "orderable": false, "targets": 2 }

I tried to use this to make the column "AÇÃO" not have an arrow anymore, but that meant the function { "orderData": [2, 1], "targets": 1 }, stops working, because column 1 needs column 2 to work.

There is another way to make sure only the first two columns will be sortable? Will I have to use CSS?
