Is there any way to edit the elements of the table created with a JavaScript function directly in the table, with a double click?

I created a function that uses three inputs to print their values in the table, as I am new to the area I still do not know much about the language.

It may be easier for a medium to send the values of tr to the inputs with a dblevent.

function adicionarItem() {
  var refNome = document.querySelector("#nome").value;
  var refCpf = document.querySelector("#cpf").value;
  var refRg = document.querySelector("#rg").value;

  var usuarioTr = document.createElement("tr");
  usuarioTr.className = "user";

  var selec = document.createElement('td');
  selec.className = 'usr';
  var input = document.createElement('input');
  input.type = 'checkbox';
  input.className = 'check';
  selec.appendChild(input);
  var nomeTd = document.createElement("td");
  var cpfTd = document.createElement("td");
  var rgTd = document.createElement("td");

  nomeTd.textContent = refNome;
  cpfTd.textContent = refCpf;
  rgTd.textContent = refRg;

  usuarioTr.appendChild(selec);
  usuarioTr.appendChild(nomeTd);
  usuarioTr.appendChild(cpfTd);
  usuarioTr.appendChild(rgTd);

  var tabela = document.querySelector("#tabela");

  tabela.appendChild(usuarioTr);
}

function removerItem() {
  ckList = document.querySelectorAll("input[type=checkbox]");
  ckList.forEach(function(el, index) {
    if (ckList[index].checked) el.parentElement.parentElement.remove();
  });
}

I do not think jQuery is the best way out of this sort of thing. It seems to me that you are trying to give a certain "reactivity" to your application and in that case I advise you to go to Vue.js .

In this link you can find a simple example of what you are looking for.

Using javascript only, it is possible to do and edit in the yes cell, here's an example:

function saveNew() {
  var $tr = document.createElement('tr');
  
  $tr.appendChild(createCell('nome'));
  $tr.appendChild(createCell('cpf'));
  $tr.appendChild(createCell('rg'));
  
  $btExcluir = document.createElement('button');
  $btExcluir.innerHTML = 'Excluir';
  $btExcluir.addEventListener('click', remove);

  $tdActions = document.createElement('td');
  $tdActions.appendChild($btExcluir);

  $tr.appendChild($tdActions);
  
  document.getElementById('data').appendChild($tr);
}

function createCell(name) {
  var $td = document.createElement('td');
  $td.innerHTML = document.querySelector('[name="' + name + '"]').value;

  $td.addEventListener('click', function() {
    var $td = this;
    $input = document.createElement('input');
    $input.type = 'text';
    $input.value = this.innerHTML;
    $input.addEventListener('blur', function() {
      $td.innerHTML = this.value;
    });
    
    this.innerHTML = '';
    this.appendChild($input);
  });

  return $td;
}

function remove() {
  var $tr = this.parentNode.parentNode;
  $tr.parentNode.removeChild($tr);
}

<table>
  <thead>
    <tr>
      <th>Nome</th>
      <th>CPF</th>
      <th>RG</th>
      <th>Ações</th>
    </tr>
  </thead>
  <tbody id="data"></tbody>
  <tfoot>
    <tr>
      <td><input type="text" name="nome"></td>
      <td><input type="text" name="cpf"></td>
      <td><input type="text" name="rg"></td>
      <td><button onclick="saveNew()">Salvar</button></td>
    </tr>
  </tfoot>
