title: Exclude a tr from parents('tr')
body: <p>I have an editable table:</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>    $('.table-salva').click(function() {
                  $(this).parents('tr').attr("contenteditable", "false");
              });
  
      $('.table-modifica').click(function() {
                  $(this).parents('tr').attr("contenteditable", "true");
              });</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;script src="https://ajax.googleapis.com/ajax/libs/jquery/1.3.1/jquery.min.js"&gt;&lt;/script&gt;
  &lt;div class="table-editable"&gt;
      &lt;table id="table" class="tabella text-center"&gt;
          &lt;thead&gt;
              &lt;tr class="hide"&gt;
                  &lt;th&gt;ID&lt;/th&gt;
                  &lt;th&gt;Data&lt;/th&gt;
                  &lt;th&gt;Entrata&lt;/th&gt;
                  &lt;th&gt;Uscita&lt;/th&gt;
              &lt;/tr&gt;
          &lt;/thead&gt;
          &lt;tbody&gt;
              &lt;tr&gt;
                  &lt;td&gt;#&lt;/td&gt;
                  &lt;td&gt;AAAA-MM-GG&lt;/td&gt;
                  &lt;td&gt;00:00&lt;/td&gt;
                  &lt;td&gt;00:00&lt;/td&gt;
                  &lt;td id="bottoni"&gt;
                      &lt;span class="table-salva"&gt;&lt;button disabled type="button" class="btn btn-danger btn-rounded btn-sm my-0"&gt;Salva&lt;/button&gt;&lt;/span&gt;
                      &lt;span class="table-modifica"&gt;&lt;button disabled type="button" class="btn btn-danger btn-rounded btn-sm my-0"&gt;Modifica&lt;/button&gt;&lt;/span&gt;
  
                  &lt;/td&gt;
              &lt;/tr&gt;
          &lt;/tbody&gt;   
      &lt;/table&gt;
  &lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>In the table, when a user click the button "Modifica" thy can edit fields and press "Salva" to save (yeah, the buttons are disabled but after they won't). 
  I want that user can't edit the field "ID", how can I modify parents('tr') to exclude first of td?  </p>
  
  <p>EDIT: I have another question. When user click on "Modifica" he can edit value of buttons too. How can I block buttons' value editing?</p>
