Sending a HTML e-mail message

Hi, I tried to get a script or something to send my e-mial in HTML format becasuse I want to add tables to line up certain text.

How do I get the e-mail to go from plain text to HTML?

Thanks

[PHP]
<?php
$con = mysql_connect("******","******","****");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}mysql_select_db("total", $con);$result = mysql_query("SELECT * FROM email");while($row = mysql_fetch_array($result))
{
$to = "$row[a1]";
$subject = "Test mail";
$message = "Hello! This is a simple email message.";
$from = "someonelse@example.com";
$headers = "From: $from";
mail($to,$subject,$message,$headers);
echo "Mail Sent.";

}mysql_close($con);
?>

[/PHP]
