Hi,
I need to reload table with new e different column:
I create first datatable:

       var tb = $("#grdScarti").DataTable({
            "ajax": "DATA/employesOBJ.txt",
            "columns": [
            { "data": "name" },
            { "data": "position" },
            { "data": "office" },
            { "data": "extn" },
            { "data": "start_date" },
            { "data": "salary" }]
           });

after I destroy e reload with new data and column:

     $('#Button1').on('click', function () {
            $.getJSON('DATA/customersOBJ.txt', null,function (json) {
                tb.destroy();
                $('#grdScarti').empty(); // empty in case the columns change
                tb = $('#grdScarti').DataTable({
                    columns: json.columns,
                    data: json.data

I look any data but without colomn name. What wrong?

    That looks like it should work to me. Could you link to a test case showing the issue please?

    I would need a link to a page showing the issue.

    Information on how to create a test page, if you can't provide a link to your own page can be found here.

    Thanks,
    Allan
