I don't know what i'm doing wrong, but using the render function on columnsDefs or columns options is not working.
I need to change the column "amount_b_f" to render a link.

• Datasource is a array of objects wich is set on "data" option manually before calling Datatables() constructor. There is no server processing.

TEST CODE

var dataTableConfig = {
        dom: 'frtipB',
        buttons: [
            {extend: "copy", text: "Copy"},
            {extend: "print", text: "Print"},
            {extend: "excel", text: "Excel"}
        ],
        "scrollY": "45vh",
        "autoWidth": false,
        "processing": false,
        "serverSide": false,
        "language": {
            "sEmptyTable": "",
            "sZeroRecords": ""
        },
        "paging": false,
        "lengthChange": false,
        "info": false,
        "searching": false,
        "aaSorting": [],
        "orderMulti": false,
        "columnDefs": [
            {className: "dt-body-right", "targets": [3]},
            {className: "dt-body-center", "targets": [1, 2]}
        ],
        "columns": [
            {
                data: {
                    "_": "type",
                    "display": "type_f"
                }
            },
            {
                data: {
                    "_": "amount_a",
                    "display": "amount_a_f"
                }
            },
            {
                data: {
                    "_": "amount_b",
                    "display": "amount_b_f"
                }
            },
            {
                data: {
                    "_": "total",
                    "display": "total_f"
                }
            }
        ],
        "data": []
    };

    dataTableConfig.data = [some data];

    $('#tabType').DataTable(dataTableConfig);
