How can HTML validation help improve the table structure in PHP files?

HTML validation can help improve the table structure in PHP files by ensuring that the HTML markup for the tables is correct and follows best practices. This can help in identifying any errors or inconsistencies in the table structure, making it easier to debug and maintain the code. By validating the HTML, you can ensure that the tables are properly structured, accessible, and semantically correct.

<!DOCTYPE html>
<html>
<head>

<body>
    <table>
        <tr>
            <th>Name</th>
            <th>Age</th>
        </tr>
        <tr>
            <td>John</td>
            <td>25</td>
        </tr>
        <tr>
            <td>Jane</td>
            <td>30</td>
        </tr>
