Show html table format in the email body in sending

Question

I’m trying to show in the body of the email an html table with the products budgeted by the customer, but it’s going all disfigured.

What I’m doing in shipping is this:

$data_pedido = date("d-m-Y");
$hora = date("H:i:s");
$mostradata = substr($data_pedido,8,2).'/'.substr($data_pedido,5,2).'/'.substr($data_pedido,0,4); 
$assunto = "Orçamento";
// E-MAIL DO EMITENTE	
$auxRemetente = "email@cliente";
$headers = "MIME-Version: 1.1". PHP_EOL;
$headers .= "Content-type: text/html; charset=iso-8859-1". PHP_EOL;
$headers .= "From: $auxRemetente". PHP_EOL; // remetente
$headers .= "Cc: $auxRemetente". PHP_EOL;
$headers .= "Return-Path: $email". PHP_EOL; // return-path	
// CONFIGURAÇÃO DO CORPO DO E-MAIL
$message = " 
Orçamento\n
Data - $mostradata - Hora - $hora\r
Nome - $nome\r
CPF/CNPJ - $cpfcnpj\r
Empresa - $empresa\r
Telefone - $telefone\r
E-mail - $email\r
Mensagem - $observacao\r";	
$message .= '

   $message .= '

To send an email in HTML format, simply inform that it is of the type text/html

In this line

$headers .= "Content-type: text/plain; charset=iso-8859-1". PHP_EOL;

Has to be

$headers .= "Content-Type: text/html; charset=iso-8859-1". PHP_EOL;

Examples:

header("Content-Type: text/plain");
echo "<b>adventistapr</b>";
// saida: <b>adventistapr</b>

header("Content-Type: text/html");
echo "<b>adventistapr</b>";
// saida: adventistapr
