My suggestion would to use PHPMailer https://github.com/PHPMailer/PHPMailer this even gives you a small example on how to use it. You can do a lot with PHPMailer besides just sending plain emails and I think it will suit you needs.
My other suggestion is to throwout that script, for whenever I see tables I cringe. 
Here’s one good example of some good form designs with the html - link on how to create a form ->
https://www.sanwebe.com/2014/08/css-html-forms-designs
Google forms if you aren’t satisfied with that link, for there are many out there that should fit your need that don’t use tables. There’s nothing wrong using tables, but tables in my opinion are better for display data ( a lot of data really easily).
I would concentrate first on just the HTML/CSS portion of the form and that is where an IDE comes in handy. I would treat Dreamweaver simply as a glorified coding and HTML/CSS IDE and nothing more.
Here’s an example of a contact form on my page, the first thing I did was concentrate on the HTML/CSS portion (THIS IS ONLY AN EXAMPLE)
[php]<?php
require_once DIR . ‘/vendor/autoload.php’;
require_once ‘lib/includes/utilities.inc.php’;
use website_project\email\EmailData as Email;
use website_project\email\Contact as SendForm;
$submit = filter_input(INPUT_POST, ‘submit’, FILTER_SANITIZE_FULL_SPECIAL_CHARS);
if (isset($submit) && $submit === ‘submit’) {
$first_name = filter_input(INPUT_POST, ‘first_name’, FILTER_SANITIZE_FULL_SPECIAL_CHARS);
$last_name = filter_input(INPUT_POST, ‘last_name’, FILTER_SANITIZE_FULL_SPECIAL_CHARS);
$name = $first_name . ’ ’ . $last_name;
$email = filter_input(INPUT_POST, ‘email’, FILTER_SANITIZE_EMAIL);
$message = filter_input(INPUT_POST, ‘comment’, FILTER_SANITIZE_FULL_SPECIAL_CHARS);
$topic = filter_input(INPUT_POST, ‘reason’, FILTER_SANITIZE_SPECIAL_CHARS);
/* Spambot check this uses a hidden Captcha technique */
$spambot = filter_input(INPUT_POST, 'subject', FILTER_SANITIZE_SPECIAL_CHARS);
$send = new SendForm(new Email($name, $email, $topic, $message, $spambot));
if (!$send->sendMail()) {
if (!$send->getName()) {
$nameError = $send->getNameError();
} else {
$displayName = $send->getName();
}
if (!$send->getEmail()) {
$emailError = $send->getEmailError();
} else {
$displayEmail = $send->getEmail();
}
if (!$send->getMessage()) {
$messageError = $send->getMessageError();
} else {
$displayMessage = $send->getMessage();
}
} else {
$success = 'Email successfully sent!'; // Set the success message if message was sent correctly:
}
}
require_once ‘lib/includes/header.inc.php’;
?>

and you can see it in action if you click on my signature link below:
I will be glad to help with the design of the form (as well as the coding) as I’m sure other will be to if you decide to go this route, just shows us what you have come up with.
