Sorting (alphabetical order) to ignore empty cells : dataTables

Question

So the question has already been asked here, but the solution doesn\'t work for me (I might do something wrong). I want to sort my tables by alphabetical order (\"type\" : \

Answer 1

Ok I found a solution for my second problem , see Here

So destroy the dataTable just before my ajax request and rebuild it on success :

    else{
        // Destroy dataTable
        $('#classement').dataTable().fnDestroy();
        $.ajax({
            type: "POST",
            url: "ajax.php",
            data: {},
            success: function(msg){
                // Reload dataTable with sorting
                $('#classement').dataTable({
                    columnDefs: [
                       {type: 'non-empty-string', targets: [2,3]} // define 'name' column as non-empty-string type
                    ]
                });
            }
        });
    }
