title: Query in a DataFrame with column names with spaces
body: <p>I have this df: <code>d = DataFrame(Symbol(&quot;Full Name&quot;) =&gt; [&quot;Mike&quot;,&quot;Paul&quot;,&quot;Andres&quot;], Symbol(&quot;Age&quot;) =&gt; 10:12)</code>
  so far so good.
  Now i want to do this Query:</p>
  <pre><code>using Query
  @from i in d begin
  @where i.Age == 11
  @select {i.&quot;Full Name&quot;, i.Age}
  @collect DataFrame
  end
  </code></pre>
  <p>But it returns an error. I think its because that &quot;Full Name&quot; field because it goes fine if the field name is just &quot;Name&quot;.  How can i fix it?</p>
