Answer 1

you can not pass object to alert. If you give object to it, it will [Object Object]. alert parameter must be string

//for Each loop code
$.each(data, function(index,value,list) { 
  alert(JSON.stringify(value)); //if you want to alert each object then use
  //data will not be accessible inside $.each you can access the same using 3rd parameter which list
  alert(JSON.stringify(list));
});

But the thing is why you gave alert in $.each and alerting same data. I'm assuming it is part of some functionality in your code. But that is not good practice to do.

Update 1.

Here is your answer with rendering table.

Code

drawTable(data);  /// call this line from your ajax success

function drawTable(data) {
    var tData = data.tblHirarchi
    for (var i = 0; i < tData.length; i++) {
        if (tData[i] != null) {
            drawRow(tData[i])
        }
    }
}

function drawRow(rowData) {
    var row = $("<tr />")
    $("#personDataTable").append(row); //this will append tr element to table... keep its reference for a while since we will add cels into it
    row.append($("<td>" + rowData[0] + "</td>"));
    row.append($("<td>" + rowData[1] + "</td>"));
    row.append($("<td>" + rowData[1] + "</td>"));
}
