具有固定列和标题的可滚动表,具有现代CSS
Rik*_*ard 13 html javascript css html-table css3
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,例如此处和此处.
我知道这可以通过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.我试图构建的功能(但是大量编写脚本)的一个例子可能是这样的.我们还可以将MutationObserver父元素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？
我想避免必须实现像这样容易破解的JavaScript解决方案:
我的想法:
a):position: fixed;在固定列中使用
问题:
<td>元素高度必须由JavaScript定义或计算.- 需要一个滚动事件监听器,我们需要以编程方式滚动固定列
b):使用div(s)来"伪造"左列,并在表格中包含可滚动内容
问题:
- div高度必须与表行高度同步
- HTML语义丢失,因为固定的"假"列不再是表格语法
c):使用N表只显示每个部分,所以我可以有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,我们可以像这样使用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');
});.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;
}<div class="table-container">
<div class="table-scroller">

</div>但是我可以不用JavaScript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.那个问题要求"只有一个左列被冻结" - 这一个的范围更广泛,它涉及固定标题,固定列和可滚动的主体.
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"JS解决方案"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.

也许你可以尝试使用最近position:sticky的实现它.或者,至少,用较少的javascript启动aproach.
