title: How do I make a two row layout for each item in Element UI
body: <p>I have a code base that uses Element UI (why does it exist?)
  And I need to have a double row for each item displayed. I need my layout to look like so... </p>
  
  <p><code>
      R1 | col1 | col2 | col3 |
         |        col4        |
      R2 | col1 | col2 | col3 |
         |        col4        |
  </code></p>
  
  <p>How can I do this in Element UI when I do not see a el-table-row element in the documentation (<a href="http://element.eleme.io/#/en-US/component/table" rel="nofollow noreferrer">http://element.eleme.io/#/en-US/component/table</a>)</p>
  
  <p>Also, I've seen their example using arraySpanMethod and objectSpanMethod but I do not understand how to get my desired result.</p>
  
  <p>Thank you for your time.</p>
