title: Empty column header in table using github markdown?
body: <p>Currently trying to format a table using github markdown. Would like to have something like: </p>
  
  <pre><code>       | col1 | col2
      -- | ---- | ----
      r1 |  r2  |  r3 
  </code></pre>
  
  <p>However markdown is forcing me to place text in the first column for the table to render. Any thoughts on how I could maintain an empty first column header?</p>
