粘贴表格标题在窗口大小调整时不改变宽度

Question

滚动时，表格顶部粘贴在顶部。

我使用的是这里提供的解决方案：css-tricks.com/persistent-headers/。

但是，当我调整窗口的大小时，粘性表头不会调整大小，并与下面的表格列的宽度相匹配。表头只是固定的大小，我不知道如何最好地解决这个问题。

function UpdateTableHeaders() { 
 
     $(".persist-area").each(function() { 
 
      var el    = $(this), 
 
       offset   = el.offset(), 
 
       scrollTop  = $(window).scrollTop(), 
 
       floatingHeader = $(".floatingHeader", this) 
 
      if ((scrollTop > offset.top) && (scrollTop < offset.top + el.height())) { 
 
       floatingHeader.css({ 
 
       "visibility": "visible" 
 
       }); 
 
      } else { 
 
       floatingHeader.css({ 
 
       "visibility": "hidden" 
 
       });  
 
       }; 
 
      }); 
 
     } 
 
      
 
     $(function() { 
 
      var clonedHeaderRow; 
 
      $(".persist-area").each(function() { 
 
       clonedHeaderRow = $(".persist-header", this); 
 
       clonedHeaderRow 
 
       .before(clonedHeaderRow.clone()) 
 
       .css("width", clonedHeaderRow.width()) 
 
       .addClass("floatingHeader"); 
 
      }); 
 
      $(window) 
 
      .scroll(UpdateTableHeaders) 
 
      .trigger("scroll"); 
 
     });

.floatingHeader { 
 
     position: fixed; 
 
     top: 0; 
 
     visibility: hidden; 
 
    } 
 
.floatingHeader th, .persist-area th, .persist-area td { 
 
     width: 14.285%; 
 
    }

我如何重新调整窗口大小的表列排列？

任何帮助将不胜感激！

尝试增加

text-align: left; 

您persist-header类。或者将它添加为内联样式。
