title: Polymer custom element containing table cells?
body: <p>I am trying to create a custom element with Polymer that contains a few table cells. I want to include it in a table row. The problem I am having is that the custom element tags break the format of the table (because the table row expects to contain table cell elements directly rather than via a sub-element).</p>
  
  <p>Is there some way of doing what I want?</p>
