title: HTML column sum
body: <p>This may not be possible at all, but I thought I'd ask. Can I sum an HTML table column to get a total? For example take the screen shot below and total the hours where the in/out is equal to "2400-Orchard."? </p>

  <p>I'm new to this stuff, so any suggestions would be great.</p>
