How to Dynamically Add/Remove Table Rows using jQuery?


In this article, we will learn how to dynamically add or remove table rows using jQuery, a popular JavaScript library, with the help of the click event listeners.

Tables are a commonly used element in web development, especially when dealing with tabular data or dynamic content. Adding or removing table rows dynamically can be a powerful feature that allows users to interact with the data in real time.

Let’s understand how to implement this with the help of some examples.

Example 1

In this example, we will have an HTML table element with some row data in it. We will have a button to add a new row at the bottom of the table, and a “remove” button corresponding to each row to remove that particular row from the table.

         }
         th,
         td {
            text-align: left;
            padding: 8px;
         }
         tr:nth-child(even) {
            background-color: #f2f2f2;
         }
         th {
            background-color: #4caf50;
            color: white;
         }
      </style>
   </head>
   <body>
      <table id="myTable">
         <thead>
            <tr>
               <th>Name</th>
               <th>Email</th>
               <th>Actions</th>
            </tr>
         </thead>
         <tbody>
            <tr>
               <td>John Doe</td>
               <td>johndoe@example.com</td>
               <td><button class="removeBtn">Remove</button></td>
            </tr>
         </tbody>
      </table>
      <button id="addRowBtn">Add Row</button>

      <script>
        $(document).ready(function () {
           // Add row button click event
           $("#addRowBtn").click(function () {
              var newRow =
              "<tr>" +
              "<td>New Name</td>" +
              "<td>New Email</td>" +
              '<td><button class="removeBtn">Remove</button></td>' +
              "</tr>";
              $("#myTable tbody").append(newRow);
           });
           // Remove row button click event
           $(document).on("click", ".removeBtn", function () {
              $(this).closest("tr").remove();
           });
         });
      </script>
   </body>
</html>

Example 2

In this example, we will follow the above code structure and generate some random emails and names using 4 different methods, like appendTo, prepend, before and after.

      <tbody>
         <tr>
            <td>John Doe</td>
            <td>johndoe@example.com</td>
            <td><button class="removeBtn">Remove</button></td>
         </tr>
      </tbody>
   </table>
   <button id="addRowBtnAppend">Add Row using appendto</button>
   <button id="addRowBtnPrepend">Add Row using prepend</button>
   <button id="addRowBtnBefore">Add Row using before</button>
   <button id="addRowBtnAfter">Add Row  using after</button>

   <script>
      $(document).ready(function () {
         // Add row button click event using appendTo()
         $("#addRowBtnAppend").click(function () {
            var newRow =
            "<tr>" +
            "<td>New Name</td>" +
            "<td>New Email</td>" +
            '<td><button class="removeBtn">Remove</button></td>' +
            "</tr>";
            $(newRow).appendTo("#myTable tbody");
         });

         // Remove row button click event
         $(document).on("click", ".removeBtn", function () {
            $(this).closest("tr").remove();
         });

         // Example 2: Add row using prepend()
         $("#addRowBtnPrepend").click(function () {
            var newRow =
            "<tr>" +
            "<td>New Name</td>" +
            "<td>New Email</td>" +
            '<td><button class="removeBtn">Remove</button></td>' +
            "</tr>";
 
            $("#myTable tbody").prepend(newRow);
         });

         // Example 3: Add row before a specific row using before()
         $("#addRowBtnBefore").click(function () {
         var newRow =
            "<tr>" +
            "<td>New Name</td>" +
            "<td>New Email</td>" +
            '<td><button class="removeBtn">Remove</button></td>' +
            "</tr>";

            $("#myTable tbody tr:first").before(newRow);
         });

         // Example 4: Add row after a specific row using after()
         $("#addRowBtnAfter").click(function () {
            var newRow =
            "<tr>" +
            "<td>New Name</td>" +
            "<td>New Email</td>" +

            "</tr>";

            $("#myTable tbody tr:last").after(newRow);
         });
      });
   </script>
</body>
