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."?

enter image description here

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.
