scrollTo and horizontal tables

问题

I am attempting to make a horizontal scrolling portfolio site. I want to users to be able to click through the images using a next/previous button as well as scrolling as per usual with the mouse and scroll bars. I am, however, having trouble implementing this using jquery.

The table is used as this is best practice in horizontal websites. I wish to use the scrollTo() plugin to allow the table to scroll forwards or backwards depending on which button is clicked.

The end product would resemble this, although I have tried to utilise the code on this site with NO luck at all!

I am lost on how to do this.

My HTML is as follows:

     <div id="content">

  <div id="contentRight">

   <ul id="direction">

    <li id="next"><a class="forward">Next</a></li>
    <li id="prev"><a class="back">Previous</a></li>

   </ul>

   <table id="work">

    <tr>

     <td id="horseOneImage" class="mainImage"><img src="media/images/horse.jpg" alt="" /></td>
     <td id="horseTwoImage" class="mainImage"><img src="media/images/horse.jpg" alt="" /></td>
     <td id="horseThreeImage" class="mainImage"><img src="media/images/horse.jpg" alt="" /></td>
     <td id="horseFourImage" class="mainImage"><img src="media/images/horse.jpg" alt="" /></td>
     <td id="horseFiveImage" class="mainImage"><img src="media/images/horse.jpg" alt="" /></td>
     <td id="horseSixImage" class="mainImage"><img src="media/images/horse.jpg" alt="" /></td>
     <td id="horseSevenImage" class="mainImage"><img src="media/images/horse.jpg" alt="" /></td>
     <td id="horseEightImage" class="mainImage"><img src="media/images/horse.jpg" alt="" /></td>

       </tr>

      </table> 

  </div>

 </div>

I have no current jQuery to add as anything I have tried is just a mess.

Any help would be great!
