    </tbody> 
    </table>  
    </div>
    </div>

使用Javascript：

    var wrapperCon= $('#wrapperCon');
    wrap.scroll(function(e){ 
        fixedHeader();          
    });

   variableHeight =  Math.abs(wrapperCon.offset().top - $('#tab-1 .loadedTable').offset().top)+19;
      function fixedHeader(){   
        $(document).find('.fixedHeader').each(function(){ 
            $(this).css('width', $(this).find('table').width());
        });
        var tabid = $(".ui-tabs-active").attr('aria-controls'),
            myTabsIdHeightt = $('#mytabsId').find('ul').height(),
            WidthDiv1Ht = $('#'+tabid).find('.WidDiv1').height();
            FinalHt = myTabsIdHeightt+WidthDiv1Ht+67;


        if(wrap.scrollTop() > variableHeight){ 
                if(ie){

                $(document).find('.fixedHeader').css({'position':'relative','top':(wrap.scrollTop()-FinalHt)+'px'});  
                }else
                {

                $(document).find('.fixedHeader').css({'position':'relative','top':(wrap.scrollTop()-FinalHt)+'px'}); 
                }
        }else{
            $(document).find('.fixedHeader').removeAttr('style');
        }           
    }
