HTML列总和

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."?

I'm new to this stuff, so any suggestions would be great.

Yes it is possible using Javascript.

Here is link to a working fiddle example.

There are three divs, each with the same class and containing a unique value.

<div class="cell">10</div>
<div class="cell">20</div>
<div class="cell">30</div>

jQuery is used to select all the elements with the class "cell" and then get the text, convert it to a number (an integer in this case) and sum the values.

var sum=0

$(".cell").each(function(i) {
   sum = sum + parseInt($(this).text());
});

console.log(sum)

The final sum is printed to the browser console.

Edit:

Here is an edited fiddle where the sum is added to the webpage using jQuery's append function.
