title: How to separate two tr's in an html table
body: <p>Is there a possibility to have a visual separator between two lines (<code>tr</code>) in an HTML table.</p>
  
  <p>I tried with a <code>&lt;br&gt;</code> but this is not valid code.</p>
  
  <p>I tried do add a padding-top to the <code>tr</code> after the break but it does not work.</p>
  
  <p>Currently I use an empty line:</p>
  
  <pre><code>&lt;tr&gt;&lt;td colspan=\"X\"&gt;&amp;nbsp;&lt;/td&gt;&lt;/tr&gt;
  </code></pre>
  
  <p>but I don't think this is the best solution, especially as I have to make sure the <code>colspan</code> is adjusted if there is a change is the number of columns.</p>
  
  <p>Is there any way to solve this?</p>
