Fill table with header from file

delphi10

I try fill to dinamic my blank table without header (th). Define columns in my file.

My version (success) not working? Wrong define columns in file?

My Txt:

{
"columns": [ 
           [ "N" ],[ "User" ],[ "Age" ] 
],
"data": [
            ["1","Jack","31"],
            ["2","Smith","29"]
]
}

My JS:

var table =  $('#example').DataTable({
        "processing": true,
        "ajax": {
            "url": file,
            "type": "POST",
            "dataType": "json",
            "success": function(json) {
                 var header;
                 $.each(json.columns, function(i, item){ 
                    header += "<th>" + item + "</th>";
                 }
                 $("#example>thead>tr").append(header);      
            }     
        }, 
        "deferRender": true, 
        "lengthChange": false, 
        "bInfo" : true,  
        "retrieve": true,
        "pageLength": 10
