How can HTML formatting be applied to PHP emails to display tabular data correctly, and what considerations should be made when sending HTML emails?

When sending PHP emails with tabular data, HTML formatting should be used to ensure the data displays correctly. This can be achieved by constructing a table within the HTML body of the email and populating it with the data. When sending HTML emails, it's important to consider the recipient's email client compatibility, use inline CSS for styling, and test the email across different devices to ensure proper display. 

<?php

// Define tabular data
$data = array(
    array('Name', 'Age', 'Email'),
    array('John Doe', 30, 'john.doe@example.com'),
    array('Jane Smith', 25, 'jane.smith@example.com')
);

// Construct HTML table
$html = '<table border="1">';
foreach ($data as $row) {
    $html .= '<tr>';
    foreach ($row as $cell) {
        $html .= '<td>' . $cell . '</td>';
    }
    $html .= '</tr>';
}
$html .= '</table>';

// Send HTML email
$to = 'recipient@example.com';
$subject = 'Tabular Data';
$message = '<html><body>';
$message .= $html;
$message .= '</body></html>';
$headers = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";

mail($to, $subject, $message, $headers);

?>
