title: How to take out the column index name in dataframe
body: <pre><code>                     Open     High    Low    Close   Volume      Adj Close
  Date                        
  1990-01-02 00:00:00  35.25   37.50   35.00   37.25   6555600     8.70
  1990-01-03 00:00:00  38.00   38.00   37.50   37.50   7444400     8.76
  1990-01-04 00:00:00  38.25   38.75   37.25   37.63   7928800     8.79
  1990-01-05 00:00:00  37.75   38.25   37.00   37.75   4406400     8.82
  1990-01-08 00:00:00  37.50   38.00   37.00   38.00   3643200     8.88
  </code></pre>
  
  <p>How can I get rid of the Date index name in the above <code>dataframe</code>? It should be in the same row as the other column names but its not which is causing problems.</p>
  
  <p>Thanks</p>
