title: Python Pandas, write DataFrame to fixed-width file (to_fwf?)
body: <p>I see that Pandas has <code>read_fwf</code>, but does it have something like <code>DataFrame.to_fwf</code>?  I'm looking for support for field width, numerical precision, and string justification.  It seems that <code>DataFrame.to_csv</code> doesn't do this.  <code>numpy.savetxt</code> does, but I wouldn't want to do:</p>
  
  <pre><code>numpy.savetxt('myfile.txt', mydataframe.to_records(), fmt='some format')
  </code></pre>
  
  <p>That just seems wrong.  Your ideas are much appreciated.</p>
