Are there any security considerations to keep in mind when including PHP pages in HTML tables?

When including PHP pages in HTML tables, it is important to sanitize any user input to prevent cross-site scripting (XSS) attacks. One way to do this is by using the htmlspecialchars() function to encode special characters before outputting them in the table cells. 

<?php
// Sanitize user input before outputting in table cells
$userInput = "<script>alert('XSS attack');</script>";
$sanitizedInput = htmlspecialchars($userInput);
echo "<table><tr><td>$sanitizedInput</td></tr></table>";
?>
