jquery sticky div gap

Question

In my page, I have a banner div and underneath that a div which I have made sticky using the sticky-kit jquery plugin.

The sticky div should be hard up against the banner div but somehow 1 pixel is creeping in which means when you scroll the text you get a rather off-putting effect.

I've made jsfiddle here and would be very grateful for any advice. I've tried other sticky plugins for jquery and they all seem to have the same problem.

HTML:

<div id="header">
    <h2>Main Banner</h2>
</div>
<div id="wrapper">
    <div id="left">
        <h2>Menu</h2>
    </div>
    <div id="right">
        <table id="tableHeader" width="100%" class="myTable" cellspacing="0">
            <tr>
                <td bgcolor="#FFFFCC"><h2>Inner Banner</h2><br>aaa</td>
            </tr>
        </table>
        <br>
