带有固定列和标题的可滚动表,带有现代CSS

如何使用现代CSS制作尽可能少的JavaScript表格?

我想要的功能是:

  • 固定柱(定位和宽度)
  • 可在X和Y轴上滚动
  • 在X轴上响应(对于非固定宽度的列)。

注意:我确实看到并分析了SO中一些最受欢迎/最常见的问题和答案,例如herehere

我知道可以使用JavaScript事件处理程序进行滚动,以便可以向下/向上移动固定列以跟随主列。我正在尝试构建的功能的一个示例(但是大量编写脚本)could be like this。我们还可以在父元素中将MutationObserver添加到表中以检测大小更改并再次计算表的大小。但这在性能上是昂贵的,而且由于CSS也在不断发展和现代化,我想知道是否有新方法......

是否有2017/2018解决方案,只有CSS或尽可能少的JS开销?

我希望避免像这样实现轻松破解的JavaScript解决方案:

我的想法:

a) :在固定列中使用position: fixed;

问题:

  • <td>元素高度必须由JavaScript定义或计算。
  • 需要滚动事件监听器,我们需要以编程方式滚动固定列

b) :使用div(s)to&#34; fake&#34;左列,表格中有可滚动的内容

问题:

  • div height必须与表行高度同步
  • 自固定&#34;假&#34;以来,HTML语义丢失了列不再是表格语法

c) :使用 N 表只显示每个部分,因此我可以使用HTML标记,但保留固定的标题/列。

问题:

  • 重复HTML x N
  • 必须同步大小并使用JavaScript滚动

使用滚动事件监听器和固定的左列,我们可以使用这样的JavaScript:

const firstColumn = [...document.querySelectorAll('table tr > *:first-of-type')];
const tableContainer = document.querySelector('.table-container');
tableContainer.addEventListener('scroll', function() {
    const currentScrollPosition = this.scrollTop * -1;
	firstColumn.forEach(el => el.style.marginTop = currentScrollPosition + 'px');
});
&#13;
.table-container {
    width: 600px;
    height: 300px;
    overflow-x: scroll;
    overflow-y: scroll;
}

.table-scroller {
    width: 1000px;
}

table {
    width: 100%;
    margin-left: -13px;
    table-layout: fixed;
    border-collapse: collapse;
    border: none;
}

table th,
table td {
    padding: 0.8em;
    border: 1px solid;
    background-color: #eeeeef;
}

table th {
    background-color: #6699FF;
    font-weight: bold;
}

table tr {
    height: 60px;
    vertical-align: middle;
}

table tr > *:first-of-type {
    position: fixed;
    width: 50px;
    margin-left: 13px;
    margin-top: 0;
    height: inherit;
}

但是我可以在没有JavaScript的情况下这样做吗?

关于可能的重复建议:

在我的问题中提到了可能的重复,它没有我正在寻找的东西。这个问题要求&#34;只有一个左栏被冻结&#34; - 这个范围更广泛,它涉及固定标题,固定列和可滚动体 另一个问题和接受的答案是2009年!我认为这个主题,我的具体范围和例子值得重新审视。另外:我的&#34; JS解决方案&#34;这只是JS如何破解的一个例子,我正在寻找现代的CSS技术来做到这一点。

也许您可以尝试使用最近的position:sticky来实现它。或者,至少,用更少的javascript来启动aproach。
