是否有跨浏览器的CSS/JavaScript技术来显示一个长HTML表,使列标题保持固定在屏幕上,而不随表体滚动。想想微软Excel中的“冻结窗格”效果。
我希望能够滚动表的内容,但总是能够在顶部看到列标题。

以下是对马克西米利安·希尔斯(Maximilian Hils)发布的答案的改进。
这个在ie11中没有任何闪烁:
var headerCells = tableWrap.querySelectorAll("thead td");
for (var i = 0; i < headerCells.length; i++) {
var headerCell = headerCells[i];
headerCell.style.backgroundColor = "silver";
}
var lastSTop = tableWrap.scrollTop;
tableWrap.addEventListener("scroll", function () {
var stop = this.scrollTop;
if (stop < lastSTop) {
// Resetting the transform for the scrolling up to hide the headers
for (var i = 0; i < headerCells.length; i++) {
headerCells[i].style.transitionDelay = "0s";
headerCells[i].style.transform = "";
}
}
lastSTop = stop;
var translate = "translate(0," + stop + "px)";
for (var i = 0; i < headerCells.length; i++) {
headerCells[i].style.transitionDelay = "0.25s";
headerCells[i].style.transform = translate;
}
});
其他回答
我意识到这个问题允许JavaScript,但这里有一个纯CSS解决方案,我还允许表水平展开。它在ie10和最新的Chrome和Firefox浏览器上进行了测试。jsFiddle的链接在底部。
HTML:
Putting some text here to differentiate between the header
aligning with the top of the screen and the header aligning
with the top of one of its ancestor containers.
<div id="positioning-container">
<div id="scroll-container">
<table>
<colgroup>
<col class="col1"></col>
<col class="col2"></col>
</colgroup>
<thead>
<th class="header-col1"><div>Header 1</div></th>
<th class="header-col2"><div>Header 2</div></th>
</thead>
<tbody>
<tr><td>Cell 1.1</td><td>Cell 1.2</td></tr>
<tr><td>Cell 2.1</td><td>Cell 2.2</td></tr>
<tr><td>Cell 3.1</td><td>Cell 3.2</td></tr>
<tr><td>Cell 4.1</td><td>Cell 4.2</td></tr>
<tr><td>Cell 5.1</td><td>Cell 5.2</td></tr>
<tr><td>Cell 6.1</td><td>Cell 6.2</td></tr>
<tr><td>Cell 7.1</td><td>Cell 7.2</td></tr>
</tbody>
</table>
</div>
</div>
而CSS:
table{
border-collapse: collapse;
table-layout: fixed;
width: 100%;
}
/* Not required, just helps with alignment for this example */
td, th{
padding: 0;
margin: 0;
}
tbody{
background-color: #ddf;
}
thead {
/* Keeps the header in place. Don't forget top: 0 */
position: absolute;
top: 0;
background-color: #ddd;
/* The 17px is to adjust for the scrollbar width.
* This is a new css value that makes this pure
* css example possible */
width: calc(100% - 17px);
height: 20px;
}
/* Positioning container. Required to position the
* header since the header uses position:absolute
* (otherwise it would position at the top of the screen) */
#positioning-container{
position: relative;
}
/* A container to set the scroll-bar and
* includes padding to move the table contents
* down below the header (padding = header height) */
#scroll-container{
overflow-y: auto;
padding-top: 20px;
height: 100px;
}
.header-col1{
background-color: red;
}
/* Fixed-width header columns need a div to set their width */
.header-col1 div{
width: 100px;
}
/* Expandable columns need a width set on the th tag */
.header-col2{
width: 100%;
}
.col1 {
width: 100px;
}
.col2{
width: 100%;
}

不太干净,但纯粹的HTML/CSS解决方案。
table {
overflow-x:scroll;
}
tbody {
max-height: /*your desired max height*/
overflow-y:scroll;
display:block;
}
针对IE8+更新 JSFiddle例子
我喜欢Maximillian Hils的回答,但我有一些问题:
这个变换在Edge或IE中不起作用,除非你把它应用到第th项上 在Edge和IE中滚动时,标题会闪烁 我的表是使用ajax加载的,所以我想附加到窗口滚动事件,而不是包装器的滚动事件
为了摆脱闪烁,我使用一个超时等待,直到用户完成滚动,然后我应用转换-所以在滚动期间头是不可见的。
我还使用jQuery编写了这篇文章,其优点之一是jQuery可以为您处理供应商前缀
var isScrolling, lastTop, lastLeft, isLeftHidden, isTopHidden;
//Scroll events don't bubble https://stackoverflow.com/a/19375645/150342
//so can't use $(document).on("scroll", ".table-container-fixed", function (e) {
document.addEventListener('scroll', function (event) {
var $container = $(event.target);
if (!$container.hasClass("table-container-fixed"))
return;
//transform needs to be applied to th for Edge and IE
//in this example I am also fixing the leftmost column
var $topLeftCell = $container.find('table:first > thead > tr > th:first');
var $headerCells = $topLeftCell.siblings();
var $columnCells = $container
.find('table:first > tbody > tr > td:first-child, ' +
'table:first > tfoot > tr > td:first-child');
//hide the cells while returning otherwise they show on top of the data
if (!isLeftHidden) {
var currentLeft = $container.scrollLeft();
if (currentLeft < lastLeft) {
//scrolling left
isLeftHidden = true;
$topLeftCell.css('visibility', 'hidden');
$columnCells.css('visibility', 'hidden');
}
lastLeft = currentLeft;
}
if (!isTopHidden) {
var currentTop = $container.scrollTop();
if (currentTop < lastTop) {
//scrolling up
isTopHidden = true;
$topLeftCell.css('visibility', 'hidden');
$headerCells.css('visibility', 'hidden');
}
lastTop = currentTop;
}
// Using timeout to delay transform until user stops scrolling
// Clear timeout while scrolling
window.clearTimeout(isScrolling);
// Set a timeout to run after scrolling ends
isScrolling = setTimeout(function () {
//move the table cells.
var x = $container.scrollLeft();
var y = $container.scrollTop();
$topLeftCell.css('transform', 'translate(' + x + 'px, ' + y + 'px)');
$headerCells.css('transform', 'translateY(' + y + 'px)');
$columnCells.css('transform', 'translateX(' + x + 'px)');
isTopHidden = isLeftHidden = false;
$topLeftCell.css('visibility', 'inherit');
$headerCells.css('visibility', 'inherit');
$columnCells.css('visibility', 'inherit');
}, 100);
}, true);
表被包装在一个div中,类table-container-fixed。
.table-container-fixed{
overflow: auto;
height: 400px;
}
我将border-collapse设置为分开,否则在翻译过程中就会丢失边界,并且我删除了表上的边界,以防止内容在滚动过程中刚好出现在边界所在的单元格上方。
.table-container-fixed > table {
border-collapse: separate;
border:none;
}
我将th背景设置为白色以覆盖下面的单元格,并添加了与表格边框相匹配的边框——使用Bootstrap样式并滚动出视图。
.table-container-fixed > table > thead > tr > th {
border-top: 1px solid #ddd !important;
background-color: white;
z-index: 10;
position: relative;/*to make z-index work*/
}
.table-container-fixed > table > thead > tr > th:first-child {
z-index: 20;
}
.table-container-fixed > table > tbody > tr > td:first-child,
.table-container-fixed > table > tfoot > tr > td:first-child {
background-color: white;
z-index: 10;
position: relative;
}
两个div,一个用于头,一个用于数据。使数据div可滚动,并使用JavaScript将标题中的列的宽度设置为与数据中的宽度相同。我认为数据列的宽度应该是固定的,而不是动态的。
