title: Set border to table tr, works in everything except IE 6 & 7
body: <p>I set the border for the table event_calendar tr to be red, it works in everything except IE 6 &amp; 7. What is wrong with my CSS?</p>
  
  <pre><code>table#event_calendar tr {
      border:1px solid red;
  }
  
  &lt;div class="content-body"&gt;
  &lt;table id="event_calendar"&gt;
      &lt;tr class="calendarHeader"&gt;
          &lt;th&gt;&lt;div class="calendarMonthLinks"&gt;&lt;a href="http://webdev.herkimer.edu/calendar/2009/03/"&gt;&amp;lt;&amp;lt;&lt;/a&gt;&lt;/div&gt;&lt;/th&gt;
          &lt;th colspan="5"&gt;&lt;h1&gt;April 2009&lt;/h1&gt;&lt;/th&gt;
          &lt;th&gt;&lt;div class="calendarMonthLinks"&gt;&lt;a class="calendarMonthLinks" href="http://webdev.herkimer.edu/calendar/2009/05/"&gt;&amp;gt;&amp;gt;&lt;/a&gt;&lt;/div&gt;&lt;/th&gt;
      &lt;/tr&gt;
      &lt;tr&gt;
          &lt;td class="calendarDayHeading"&gt;Sunday&lt;/td&gt;
          &lt;td class="calendarDayHeading"&gt;Monday&lt;/td&gt;
          &lt;td class="calendarDayHeading"&gt;Tuesday&lt;/td&gt;
          &lt;td class="calendarDayHeading"&gt;Wednesday&lt;/td&gt;
          &lt;td class="calendarDayHeading"&gt;Thursday&lt;/td&gt;
          &lt;td class="calendarDayHeading"&gt;Friday&lt;/td&gt;
          &lt;td class="calendarDayHeading"&gt;Saturday&lt;/td&gt;
      &lt;/tr&gt;
  &lt;/table&gt;
  &lt;/div&gt;
