How to store data in an array in row/column format using javascript

I am trying to bring all the columns of a table from database and want to store whole data (retrieved from webform) in an array with column names.
For Example Following is my database Table.
StudentName Roll_No Subject Marks
Rock 101 English 98

I want to store above data in same structure in my array.
Here is my code...

function Insert(FormName, DivName) {
    $.ajax({
        type: "POST",
        url: "" + FormName + ".aspx/GetData",
        data: '{}',
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function (response) {
            var xmlDoc = $.parseXML(response.d);
            var xml = $(xmlDoc);
            var Records = xml.find("Table");
            if (Records.length > 0) {
             
                var DetailData = new Array();  // I want to store table in same structure in this array.
                
                $.each(Records, function () {
                    var record = $(this);
                    var ColName = record.find("Column_name").text();   //Getting Column names from database
                    var ColValue = GetColumnsValue(ColName, DivName);  // getting columns value in webform.

                });
            }
        },
        error: function (d) {
            alert(d.responseText);
        }
    });
}

Solution

You can use this code

function Insert(FormName, DivName) {
    $.ajax({
        type: "POST",
        url: "" + FormName + ".aspx/GetData",
        data: '{}',
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function (response) {
            var xmlDoc = $.parseXML(response.d);
            var xml = $(xmlDoc);
            var Records = xml.find("Table");
            if (Records.length > 0) {

                var DetailData = []; 

                var rowData = {};

                $.each(Records, function () {
                    var record = $(this);
                    var ColName = record.find("Column_name").text();   
                    var ColValue = GetColumnsValue(ColName, DivName); 

                    rowData[ColName] = ColValue;
                });

                DetailData.push(rowData);
                console.log(DetailData);
            }
        },
        error: function (d) {
            alert(d.responseText);
        }
    });
}

After execution, DetailData will look like this:

[ { "StudentName": "Rock", "Roll_No": "101", "Subject": "English", "Marks": "98" } ]
