Background image hover effect outside of containing element

I am trying to apply a background image hover effect on each row in my css table but need it to appear to the left of the containing element.

View image http://www.weiserwebworld.com/images/view.gif

Any ideas?

JS:

$(function() {
    $(".table-row").hover(function() { 
        $(this).addClass("highlight");
    }, function() {
        $(this).removeClass("highlight");
    })
})

CSS:

#container {
    width: 660px; 
    margin: 20px auto;
}

div .table {
    display: table;
    border: 1px red solid;  
}
div .table-row {
    display: table-row;
}
div .table-cell {
    display: table-cell;
    width: 145px;
    padding: 10px;
    vertical-align: top;

}
.highlight {
    cursor: pointer;
    background-image: url('click-to-view.png');
    background-position: 0 center;
    background-repeat: no-repeat;

}

HTML:

<div id="container">
    <div class="table">
        <div class="table-row">
            <div class="table-cell">Ralph Kramden</div>
            <div class="table-cell">Truck Driver</div>
            <div class="table-cell">8/17/2010</div>
            <div class="table-cell">N/A</div>
        </div>
        <div class="table-row">
            <div class="table-cell">Ralph Kramden</div>
            <div class="table-cell">Truck Driver</div>
            <div class="table-cell">8/17/2010</div>
            <div class="table-cell">N/A</div>
        </div>
    </div>
</div>

First, throw away this:

$(function() {
    $(".table-row").hover(function() { 
        $(this).addClass("highlight");
    }, function() {
        $(this).removeClass("highlight");
    })
})

It is an abomination.

Then change the CSS selector .highlight to .table-row:hover. As you clearly don't care about IE6 (where :hover only worked on a elements), there's nothing wrong with using :hover.

Now to the rest of the problem.

The technique that I would use for this is the before or after pseudo-element. Something like this:

.table-row {
    position: relative; /* So that the position: absolute on the "click to view" makes it relative to the table row */
}
.table-row:hover:after {
    position: absolute;
    left: -80px; /* Adjust as desired */
    content: url(click-to-view.png); /* This makes it an image */
}

There's plenty of tweaking that can be done with this, but that's the general idea. No demo on jsfiddle as I can't be bothered doing the table structure or getting an image for it.

You can do this in pure CSS.

This is quick and dirty, you'll have to tweak it to how you want, but the general idea is:

If you give your row an id () you can add a CSS styles like this:

.overlay {
   display: none;
   position: absolute;
   left: -30px; //makes it appear left of box, even though it's technically "in" box.
}

#table-row1:hover .overlay {
    display; block;  //Causes div to appear.
}

Now, simply add with the image you want, that will appear as you roll over the row.

Note that the class=overlay div MUST be placed INSIDE of the id=table-row1 div or the hover-appear will not work!

I would also recommend redoing this using tags with the same :hover approach, as your current method of divs with table properties could get unwieldy very fast.

You need to put your image in a DIV, then position the DIV relative to the row. Backgrounds cannot go outside the boundary of their container.
