I have a ListView that I want to output both a THEAD and a TBODY element.  Currently it just outputs a TABLE and TBODY followed by the heading and data contents in separate TR elements.  My LayoutTemplate is below.  What am I missing?

        <LayoutTemplate>
            <table id="Table1" runat="server" border="0" cellpadding="0" cellspacing="0" width="99%" class="scrollTable">
                <thead class="fixedHeader">
                    <tr>
                        <th id="Th1" runat="server">
                            LogID</th>
                        <th id="Th2" runat="server">
                            LoginDateTime</th>
                        <th id="Th3" runat="server">
                            LogType</th>
                        <th id="Th4" runat="server">
                            RecordID</th>
                        <th id="Th5" runat="server">
                            VendorID</th>
                        <th id="Th6" runat="server">
                            InsuranceID</th>
                        <th id="Th7" runat="server">
                            LogSubType</th>
                    </tr>
                </thead>
                <tbody class="scrollContent">
                    <tr ID="itemPlaceholder" runat="server">
                    </tr>
                </tbody>
            </table>
        </LayoutTemplate>
