title: Add new field to POS ticket of the restaurant module
body: <p>I want to add a new field that contains the name of the table that had that order in the pos receip of the resaturant module, I already have searched for similar examples but couldn't solve this </p>
  
  <p>I first added the variable that containes the name of the table in the models fields (this variable is in the restaurant_table class so I have done an inheritance to the restaurant_printer class) :</p>
  
  <p>pos_restaurant\static\src\js\multiprint.js</p>
  
  <pre><code>model: 'restaurant.printer',
  
  fields: ['name','proxy_ip','product_categories_ids','name_table'],
  </code></pre>
  
  <p>seconde I have added this line in the pos_restaurant\static\src\xml\printbill.xml</p>
  
  <pre><code>&lt;div id="name_table" style="text-align:center;"&gt;&lt;/div&gt;
  </code></pre>
  
  <p>but nothing had changed in the ticket any ideas please?</p>
