Are there any potential pitfalls to consider when implementing column headers that stay fixed while scrolling in PHP?

When implementing column headers that stay fixed while scrolling in PHP, one potential pitfall to consider is the performance impact on the page load time. If the table contains a large amount of data, fixing the column headers can lead to slower rendering times. To mitigate this issue, it is important to optimize the code and only fix the headers when necessary, such as when the user scrolls past a certain point. 

// Example PHP code snippet to implement fixed column headers while scrolling

echo '<div style="overflow-x:auto;">';
echo '<table>';
echo '<thead style="position: sticky; top: 0; background-color: #f1f1f1;">';
echo '<tr>';
echo '<th>Header 1</th>';
echo '<th>Header 2</th>';
echo '<th>Header 3</th>';
echo '</tr>';
echo '</thead>';
echo '<tbody>';

// Loop through your data and display it in the table
foreach ($data as $row) {
    echo '<tr>';
    echo '<td>' . $row['column1'] . '</td>';
    echo '<td>' . $row['column2'] . '</td>';
    echo '<td>' . $row['column3'] . '</td>';
    echo '</tr>';
}

echo '</tbody>';
echo '</table>';
echo '</div>';
