title: Convert a tab- and newline-delimited string to pandas dataframe
body: <p>I have a string of the following format:</p>
  
  <pre><code>aString = '123\t456\t789\n321\t654\t987 ...'
  </code></pre>
  
  <p>And I would like to convert it to a pandas DataFrame</p>
  
  <pre><code>frame:
    123 456 789
    321 654 987
    ...
  </code></pre>
  
  <p>I have tried to convert it to a Python list:</p>
  
  <pre><code>stringList = aString.split('\n')
  </code></pre>
  
  <p>which results in:</p>
  
  <pre><code>stringList = ['123\t456\t789',
                '321\t654\t987',
                ...
               ]
  </code></pre>
  
  <p>Have no idea what to do next.</p>
