I am not understanding the data structures.

I am bringing back some data from an Ajax call.

req = Ajax("http://xxx.com.myphp", "GET", 'someData',quotesReturned);
When I output it to the console I get the array and use it as follows.

var dataSet =  [["566","1318","2017-11-08","http:\/\/www.toolfolks.com\/techy\/quoteImages\/566_1.jpg",null,"Job lot Zandra Rhodes bags.

this works okay.

  tableObject  =  $('#dtQuotes').DataTable( {
        data: dataSet,
            
 columns: [
            { title: "Name" },
            { title: "Position" },
            { title: "Office" },
            { title: "Extn." },
            { title: "Start date" },
            { title: "Salary" }
]


} );

If I use dataSet = req.responseText; ie the returned data directly I get the error

DataTables warning: table id=dtQuotes - Requested unknown parameter '1' for row 0, column 1. For more information about this error, please see http://datatables.net/tn/4

Is there a structure difference between the data I get back and when it is outputted to the console. ?

Cheers
