<div class="table-head">
     <table>
         <colgroup>
             <col style="width: 80px;" />
             <col />
         </colgroup>
         <thead>
             <tr><th>序號</th><th>內容</th></tr>
         </thead>
     </table>

     <div class="table-body">
     <table>
         <colgroup><col style="width: 80px;" /><col /></colgroup>
         <tbody>
             <tr><td>1</td><td>我只是用來測試的</td></tr>
