想法：
创建一个用于显示数据的 adwords 样式表，并带有固定的、类似流体的标题。

方法：
克隆一个表格标题，为其单元格赋予实际表格的相应宽度，当表格标题滚动出视口（垂直）时固定到顶部，水平滚动时向左滚动标题。

问题：
如标题中所述。显然，webkit 和 IE 计算单元格的方式与 Mozilla 和 Opera 不同（我猜？）（在这两者中一切正常，尽管每隔一段时间，当窗口只有“正确”宽度时，标题就会向右突出一个像素）。

的HTML：

备注：

  • 将表格宽度设置为 100% 会使单元格中的文本渗入某些浏览器中的相邻单元格；
  • 某些单元格具有百分比宽度，因为否则它们会占用太多空间（即表格中的最后一列“est.bid first call”）不应“占用”其他“更重要”列的空间，例如第一列；
  • 出于布局目的，整个页面已被投射到表格中。管理这种布局会使 html/css 变得不必要的笨重和笨重；
  • 支持所有现代浏览器和 IE8+。

到目前为止，我已经尝试了很多方法，但是由于我对 js/jq 的了解非常有限，所以我无法找到适合这个问题的解决方案。

请帮忙？

终于解决了。问题显然是 jquery 的 .width 函数舍入子像素的结果。

申请

document.defaultView.getComputedStyle(e, null).width

解决了。
