What are the best practices for creating a fixed header in a table using PHP?

When displaying a table with a large number of rows, it can be helpful to have a fixed header so that users can always see the column names as they scroll through the data. This can be achieved by using CSS to set the header row to position: fixed and then adjusting the width of the header cells to match the width of the corresponding data cells.

<table>
  <thead style="position: fixed;">
    <tr>
      <th style="width: 100px;">Column 1</th>
      <th style="width: 150px;">Column 2</th>
      <th style="width: 200px;">Column 3</th>
    </tr>
  </thead>
  <tbody>
    <?php
    // Your PHP code to generate table rows goes here
    ?>
  </tbody>
</table>
