What Are DataTables?

DataTables is a popular jQuery plugin that makes it simple to add advanced interaction controls to your HTML tables. It transforms your static HTML tables into dynamic, feature-rich tables that allow searching, sorting, filtering, and much more, improving the user experience.

Setting Up DataTables

Before diving into code, you’ll need to include the necessary files and initialize DataTables.

<!-- Include jQuery -->
<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>

<!-- Include DataTables CSS -->
<link rel="stylesheet" type="text/css" href="https://cdn.datatables.net/1.11.6/css/jquery.dataTables.min.css">

<!-- Include DataTables JavaScript -->
<script type="text/javascript" charset="utf8" src="https://cdn.datatables.net/1.11.6/js/jquery.dataTables.min.js"></script>

<script>
  $(document).ready( function () {
    $('#myTable').DataTable();
  });
</script>

Make sure you replace #myTable with the appropriate HTML table selector for your project.

Using DataTables with JavaScript Arrays

One of the most straightforward ways to use DataTables is with JavaScript arrays. Suppose you have a predefined dataset in your script. Here’s how you can use it:

<table id="myTable" class="display">
  <thead>
    <tr>
      <th>Name</th>
      <th>Age</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>John</td>
      <td>25</td>
    </tr>
    <tr>
      <td>Mary</td>
      <td>30</td>
    </tr>
    <!-- Add more rows here -->
  </tbody>
</table>

Using DataTables with JSON Data from AJAX

For dynamic data retrieval, you can use JSON from an AJAX GET or POST request. Here’s a simple example of how you can do this using jQuery’s AJAX:

$(document).ready( function () {
  $('#myTable').DataTable({
    "ajax": "yourData.json",
    "columns": [
      { "data": "Name" },
      { "data": "Age" }
    ]
  });
});

In this example, “yourData.json” represents the endpoint that serves your JSON data.

In a previous post, we also discussed how to use DataTables with PHP. You may also want to check that.

Customizing DataTables

DataTables is highly customizable. You can change the look, behavior, and functionality to fit your project’s needs. Visit the DataTables documentation for extensive customization options.

Conclusion

DataTables in JavaScript provides a powerful and user-friendly way to handle tabular data on your web projects. By understanding how to initialize and use DataTables with JavaScript arrays or JSON data from AJAX, you’re equipped to enhance your web applications with interactive and responsive tables.

Incorporating DataTables not only improves the user experience but also makes your data more accessible and meaningful. Explore the endless possibilities DataTables offer, and unlock your full potential as a developer!
