        display +
        `<tr>
            <th scope="row">${index + 1}</th>
            <td>${element.first}</td>
            <td>${element.second}</td>
            <td>${element.third}</td>
            <td><button type="button" id="${index}" onclick="deleteNode(this.id)" class="btn btn-danger">Delete</button></td>
