use <thead>

<input type="text" id="searchinputtext" class="form-control" placeholder="search">    <span id="errmsgnovideos"></span> <table class="mytable1 table table-bordered table-hover" id="videosfromtagstable"> <thead>     <tr class="existingvideos">          <th width="20%">name</th>          <th width="35%">file</th>          <th width="30%">course</th>          <th width="15%">seepz</th>       </tr> </thead>    <tbody class="connectedsortable ui-sortable">        <tr video-id="48" title="" class="newvideos exercises-add-table-content">          <td>dsada</td>          <td><a href="xxx" target="_blank">dftyr.mp4</a></td>          <td>             <span class="btn btn-sm btn-success btn-circle">five</span>          </td>          <td><i class="fa fa-check"></i></td>       </tr>       <tr video-id="49" title="" class="newvideos exercises-add-table-content">          <td>fds</td>          <td><a href="xxx" target="_blank">dftyr.mp4</a></td>          <td>             <span class="btn btn-sm btn-success btn-circle">five</span>          </td>          <td><i class="fa fa-check"></i></td>       </tr>    </tbody> </table>
