<table id="modx-abtn-save" cellspacing="0" class="x-btn x-btn-text bmenu x-btn-noicon" style="width: auto;">
    <tbody class="x-btn-small x-btn-icon-small-left">
    <tr>
        <td class="x-btn-tl"><i>&nbsp;</i></td>
        <td class="x-btn-tc"></td>
        <td class="x-btn-tr"><i>&nbsp;</i></td>
    </tr>
    <tr>
        <td class="x-btn-ml"><i>&nbsp;</i></td>
        <td class="x-btn-mc"><em class="" unselectable="on">
            <button type="button" id="ext-gen389" style="" class=" x-btn-text">Save</button>
        </em></td>
        <td class="x-btn-mr"><i>&nbsp;</i></td>
    </tr>
    <tr>
        <td class="x-btn-bl"><i>&nbsp;</i></td>
        <td class="x-btn-bc"></td>
        <td class="x-btn-br"><i>&nbsp;</i></td>
    </tr>
    </tbody>
</table>
