窗口调整大小时粘滞表标题不更改宽度

Question

当向下滚动时，我在顶部有一个粘性的表头。

我正在使用此处提供的解决方案：css-tricks.com/persistent-headers /.

但是，当我调整窗口大小时，粘性表标题不会调整大小并匹配下面表列的宽度。表格标题只是固定大小，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");
        });

＆＃13;

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

Answer 1

尝试添加

text-align: left;

到你的persist-header课程。或者将其添加为内联样式。
