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%;
}
