title: disable autosort of dataframe pandas
body: <p>I'm creating dataframe </p>
  
  <pre><code>ohlc = pd.DataFrame( { 'date':[date2num(dup.parse(x)) for x in rates['date']],
                         'open':rates['open'],
                         'high':rates['high'],
                         'low':rates['low'],
                         'close':rates['close'] }  )
  </code></pre>
  
  <p>and i expect following order of columns (date, open, high, low, close).
  But something triggered and i get such an order (close, date, high, low, open).</p>
  
  <p>please advise me, how can turn off sorting or way to fix it.</p>
