Merging two objects of Ajax response into one column

beginneer

Hi,
I need to merge information from two lists received in ajax response and display their data in one column. this link(https://datatables.net/examples/basic_init/hidden_columns.html) explains how to hide columns. But I need to get data of hidden column and append it to another column, How do I do that. below is my code. column 3 is hidden but column 4 does not contain data from list1.

$j('#mydataTable').DataTable({
            "processing": true,
            "serverSide": true,
            "ajax": "datasource.json",
            "columns": [
                {"data": "name"},
                {"data": "office"},
                {"data": "phone"},
                {"data": "list1"},
                {"data": "list2"}
                ],
                columnDefs: [
                             {
                                 targets: [ 3,4],
                                 "orderable": false,
                                 render: function ( data, type, row ) {
                                     console.log("data : "+data);
                                     return data;
                                 }
                             },
                             {
                                 targets: [3],
                                 "orderable": false,
                                 "visible": false,
                                 "searchable": false
                             }
                            ]
        });

Thanks I found it, Its easy,
{
targets: [ 4],
"orderable": false,
render: function ( data, type, row ) {
return data+row.list1;
}
},
