title: Django-tables2: Provide a list of dictionary, how to generate a column for each dictionary entry
body: <p>I know if we have a model class, we can make a generate table and use:</p>
  
  <pre><code>class Meta:
      model = MyModel
  </code></pre>
  
  <p>To display every field.</p>
  
  <p>Now say if I have a list of dictionaries, instead of model, is there a similar way to do so?</p>
  
  <p>(Since there are so many different dictionaries, which might be dynamically created, I don't wanna create a customized one each time :-))</p>
