Non sorting rows

Non sorting rows


Does anyone know if it's possible to remove a row in a sortable table
from being included in the sorting?
Given the following:
<table border="1" id="agentTable">
    <thead>
        <tr>
            <th>ID</th>
            <th>Name</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td></td>
            <td><input type="text" /></td>
        </tr>
        <tr>
            <td>1</td>
            <td>Property Owl</td>
        </tr>
        <tr>
            <td>2</td>
            <td>Amelia King</td>
        </tr>
        <tr>
            <td>3</td>
            <td>Agent X</td>
        </tr>
        <tr>
            <td>4</td>
            <td>Agent ORaNge</td>
        </tr>
        <tr>
            <td>5</td>
            <td>FBI Agent</td>
        </tr>
        <tr>
            <td>6</td>
            <td>Moulder</td>
        </tr>
        <tr>
            <td>7</td>
            <td>Scully</td>
        </tr>
    </tbody>
</table>
I would like to keep the input row at the top at all times.
Any ideas or suggestions?
Cheers.
