title: How do you remove the column name row when exporting a pandas DataFrame?
body: <p>Say I import the following Excel spreadsheet into a dataframe:</p>
  
  <pre><code>Val1 Val2 Val3
  1     2    3 
  5     6    7 
  9     1    2
  </code></pre>
  
  <p>How do I delete the column name row (in this case <code>Val1, Val2, Val3</code>) so that I can export a csv with no column names, just the data?</p>
  
  <p>I have tried <code>df.drop()</code> and <code>df.ix[1:]</code> and have not been successful with either.</p>
