title: Merge two HTML table cells
body: <p>I'm creating a table in HTML and I'd like to have my top cell be the width of two. Here's a rough drawing:</p>
  <pre><code>__________________________________________
  |                HEADER                  |
  |                                        |
  ==========================================
  |                  ||                    |
  |     CONTENT      ||       CONTENT      |
  |                  ||                    |
  ------------------------------------------
  </code></pre>
  <p>Is there a way to accomplish this in HTML?</p>
