title: Does a <tr> have to be inside a <tbody>
body: <p>Does a table row (<code>&lt;tr&gt;</code>) have to be in a table body (<code>&lt;tbody&gt;</code>), if the table has a table body, or can it exist outside of the table body?</p>
  
  <pre><code>&lt;table&gt;
      &lt;tr&gt;
        &lt;td colspan='2'&gt;...&lt;/td&gt;
      &lt;/tr&gt;
  
      &lt;tbody&gt;
        &lt;tr&gt;
          &lt;td&gt;...&lt;/td&gt;
          &lt;td&gt;...&lt;/td&gt;
        &lt;/tr&gt;
      &lt;/tbody&gt;
  
      &lt;tr&gt;
        &lt;td colspan='2'&gt;...&lt;/td&gt;
      &lt;/tr&gt;
  
      &lt;tbody&gt;
        &lt;tr&gt;
          &lt;td&gt;...&lt;/td&gt;
          &lt;td&gt;...&lt;/td&gt;
        &lt;/tr&gt;
      &lt;/tbody&gt;
  
  &lt;/table&gt;
