title: Creating table rows with wide borders without bleeding into adjacent rows
body: <p>I have an HTML table of tickets listings (e.g. <a href="http://seatgeek.com/event/show/23634/buffalo-bills-vs-tennessee-titans/" rel="nofollow noreferrer">http://seatgeek.com/event/show/23634/buffalo-bills-vs-tennessee-titans/</a>).  I'd like to highlight certain rows with a 2px border.  The problem is that this is bleeding into adjacent cells and covering up other borders.  </p>
  
  <p>For example, I have a 1px bottom border on the first row of cells (to designate that it's a header).  If I try applying a 2px border to the second row, then it covers up border in the first.</p>
  
  <p>My first reaction was to set a margin for the troublesome, but I've been hunting around for a solution, and it looks like that's not possible.  Is there another solution?</p>
