<table>
<tr>
<td>

AutoGenerateColumns="false">
<Columns>
<SharePoint:SPBoundField HeaderStyle-BackColor="#BDA65A" HeaderText="Label Number"
DataField="Label Number" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Left">
</SharePoint:SPBoundField>
<asp:BoundField HeaderStyle-BackColor="#BDA65A" HeaderText="Description" HtmlEncode="false"
HeaderStyle-HorizontalAlign="Center" DataField="Description" ItemStyle-HorizontalAlign="Left"
/>
<SharePoint:SPBoundField HeaderStyle-BackColor="#BDA65A" HeaderText="Sequence Number"
HeaderStyle-HorizontalAlign="Center" DataField="Sequence Number" ItemStyle-HorizontalAlign="Left">
