title: Python tabulate format: want to display the table with one blank element
body: <p>I was trying to use Python's tabulate format. I want to get my data in the following way:</p>
  <pre><code>x    1
  y    2   3
  z    4   5
  </code></pre>
  <p>My code is like this:</p>
  <pre><code>from tabulate import tabulate
  table = [[&quot;x&quot;, 1], [&quot;y&quot;, 2, 3], [&quot;z&quot;, 4, 5]]
  print tabulate(table)
  </code></pre>
  <p>But, with this, I am getting an output:</p>
  <pre><code>-  -
  x  1
  y  2
  z  4
  -  -
  </code></pre>
  <p>That means it suppresses the second data for every attribute. Is there any solution for this?</p>
