title: Error on pandas.read_hdf
body: <p>I created an HDF5 file with:</p>
  
  <pre><code>pfad = "E:\Geld\Handelssysteme\Kursdaten\Ivolatity/Daten Monatsoptionen/ODAX_alles.h5"
  df.to_hdf(pfad,'df', format='table')
  </code></pre>
  
  <p>Now I want to read and put a portion of the table back into a dataframe without reading all of the lines in the file.</p>
  
  <p>I tried </p>
  
  <pre><code>df=pandas.read_hdf('pfad', 'df', where = ['expiration&lt;expirations[1] and expiration&gt;=expirations[0]'])
  </code></pre>
  
  <p>where expirations is a list that contains datetime64[ns] values and I want to get a dataframe where the values in column "expiration" are between <code>expirations[1]</code> and <code>expirations[0]</code>.</p>
  
  <p>However, I get a <code>KeyError: 'No object named df in the file'</code></p>
  
  <p>What would the right syntax be?</p>
