Vue is not rendering table with v-for, how to solve?

My code is not rendering the list produtos defined by Vue. When I remove the template <pd> out of the table it renders, I looked for solutions and saw that in the very document of vuejs there is a trace with the tag table Exceptions in the Analysis of the DOM Template, but I couldn’t figure out how to use the v-for in which case, someone could help me fix the problem?
Below is the code.

Vue.component('pd', {
    props: ['nome', 'quantia'],
    template: '<tr><td>{{ nome }}</td><td>{{ quantia }}</td></tr>'
});

var app = new Vue({
    el: '#listaProdutos',
    data: {
        produtos : [
            { id: 0, nome: 'Camisa Regata', quantia: 2},
            { id: 1, nome: 'Bermuda Jeans', quantia: 5},
            { id: 2, nome: 'Casaco Preto', quantia: 1},
        ]
    }

});

EDIT: I changed the answer to be more in line with the Vue documentation.

There are two ways: Involving in a tag <template> which is a valid tag inside a tbody and using the attribute is (recommended).

Source: https://br.vuejs.org/v2/guide/components.html#Disclaimers-na-Parse-do-Template-DOM

Vue.component('pd', {
  props: ['nome', 'quantia'],
  template: '<tr><td>{{ nome }}</td><td>{{ quantia }}</td></tr>'
});

var app = new Vue({
  el: '#listaProdutos',
  data: {
    produtos: [{
        id: 0,
        nome: 'Camisa Regata',
        quantia: 2
      },
      {
        id: 1,
        nome: 'Bermuda Jeans',
        quantia: 5
      },
      {
        id: 2,
        nome: 'Casaco Preto',
        quantia: 1
      },
    ]
  }

});
