What could be causing the output to be displayed above the table instead of within the column in the PHP function?

The issue of the output being displayed above the table instead of within the column in the PHP function could be caused by echoing the output before the table is generated. To solve this, you should store the output in a variable and then echo it within the column where you want it to be displayed.

<?php
function display_output_in_column() {
    $output = 'Output to be displayed within the column';
    
    echo '<table>';
    echo '<tr>';
    echo '<td>' . $output . '</td>';
    echo '</tr>';
    echo '</table>';
}

display_output_in_column();
?>
