在数据表中单击单击选择行并将所选数据导出为Excel

Question

I am using a datatable to populate data into it. The requirement is that this data is to be exported. The User can export "Selected Rows" or "All" the Data at once. I have used the datatable export Excel functionality which creates buttons two buttons "Export All" and "Export Selected" which exports the data. Export All works fine but when I use the functionality of datatable to select rows using "select:true", I have to use the CTRL Button to select multiple rows, and it works fine and exports data as well but I don't want this, so I created a click event on the table.tr which adds the selected class to TR, which selects the row, but after selecting the row, when I export the data, nothing export's, the excel is blank. What may be the issue, "select:true" adds class selected to the TR and I am also adding class selected to the TR on click but why the data is not exporting, can anyone has idea about this. I have also created a fiddle: Datatable Fiddle My code is as:

<table id="example" cellspacing="0" width="100%" class="display  row-border nowrap table-striped responsive-utilities jambo_table">
    <thead>
        <th>Name</th>
        <th>Company</th>
        <th>Office Phone</th>
        <th>Country</th>
        <th>Action</th>
     </thead>
     <tbody>
        <tr>
            <td>Test 1</td>
            <td class="dt-center">1</td>
            <td class="dt-center">1</td>
            <td class="dt-center">United Kingdom</td>
            <td class="dt-center not-exported">Edit Button</td>
        </tr>
        <tr>
            <td>Test 2</td>
            <td class="dt-center">2</td>
            <td class="dt-center">2</td>
            <td class="dt-center">United Kingdom</td>
            <td class="dt-center not-exported">Edit Button</td>
        </tr>
        <tr>
            <td>Test 3</td>
            <td class="dt-center">3</td>
            <td class="dt-center">3</td>
            <td class="dt-center">United Kingdom</td>
            <td class="dt-center not-exported">Edit Button</td>
        </tr>
    </tbody>

                }
            },
            {
                extend: 'excelHtml5',
                text: 'Export selected',
                exportOptions: {
                    columns: ':visible:not(.not-exported)',
                    modifier: {
                        selected: true

            },
            'colvis'
        ],
      // select: true   
    });

     $('#example tbody').on('click', 'tr', function () {
        $(this).toggleClass('selected');
     });
  });
