title: How to shade every other table row that spans across multiple rows?
body: <p>I am trying to shade every other row that spans across multiple rows next to it while also shading those rows (not each). How would I do this with just CSS if it is possibly at all?</p>
  
  <pre><code>----------------------------------------------
  | HEADER | HEADER | HEADER | HEADER | HEADER | 
  ----------------------------------------------
  |        | COLUMN | COLUMN | COLUMN | COLUMN | 
  | COLUMN |------------------------------------
  |        | COLUMN | COLUMN | COLUMN | COLUMN | 
  ----------------------------------------------
  |        | COLUMN | COLUMN | COLUMN | COLUMN | 
  |        |------------------------------------
  | COLUMN | COLUMN | COLUMN | COLUMN | COLUMN | 
  | shaded |------------------------------------
  |        | COLUMN | COLUMN | COLUMN | COLUMN | 
  ----------------------------------------------
  | COLUMN | COLUMN | COLUMN | COLUMN | COLUMN | 
  ----------------------------------------------
  |        | COLUMN | COLUMN | COLUMN | COLUMN | 
  | COLUMN |------------------------------------
  | shaded | COLUMN | COLUMN | COLUMN | COLUMN | 
  ----------------------------------------------
  </code></pre>
  
  <p>In case it wasn't clear, the rows next to shaded rowspan should be shaded all together as well.</p>
