Google应用程序脚本：如何为自动电子邮件添加一些样式？

我在Google应用程序脚本中有此代码，可以在Google表单完成后自动接收电子邮件，但是我尚无法编辑样式。我尝试过的内联样式不起作用。我想添加一张桌子，更改我的字体甚至颜色。

代码：

function formSubmitReply(e) {

var alUser = e.values[1];
var entity = e.values[3];
var language = e.values[2];
var category = e.values[4];
var title = e.values[5];
var questions = e.values[6];
var attach = e.values[7];
var entityEn = e.values[8];
var categoryEn = e.values[9];
var titleEn = e.values[10];
var questionsEn = e.values[11];
var attachEn = e.values[12];

var userEmail = "[email protected]" + "," + "[email protected]";    

var msgFr = "<p>You have received a new inquiry</p>" + 
          "<h4>AL user: </h4>" + alUser + 
          "<h4>Entité </h4>" + entity + 
          "<h4>Langue préférée: </h4>" + language +
          "<h4>Catégorie de la demande: </h4>" + category + 
          "<h4>Titre de la demande: </h4>" + title + 
          "<h4>Contenu de la demande  </h4>" + questions + "<br>" +
          "<h4>Ajouter: </h4>" + attach + "<br>";     

var msgEn = "<p>You have received a new inquiry</p>" + 
          "<h4>AL user: </h4>" + alUser + 
          "<h4>Entity: </h4>" + entityEn + 
          "<h4>Preferred Language: </h4>" + language +
          "<h4>Category: </h4>" + categoryEn + 
          "<h4>Title: </h4>" + titleEn + 
          "<h4>Question: </h4>" + questionsEn + "<br>" +
          "<h4>Attachments: </h4>" + attachEn + "<br>";          

MailApp.sendEmail({
  to: userEmail,
  subject: 'NAM HR Mailbox | ' + category,
  htmlBody: (language=="English") ? msgEn : msgFr
});

}
