我想在表格单元格中使用CSS文本溢出,这样,如果文本太长而不能适合一行,它将用省略号剪辑,而不是包装到多行。这可能吗?
我试了一下:
td {
overflow: hidden;
text-overflow: ellipsis;
white-space: nowrap;
}
但是white-space: nowrap似乎使文本(及其单元格)不断向右扩展,将表的总宽度推到容器的宽度之外。但是,如果没有它,当文本到达单元格边缘时,它将继续换行为多行。

为什么会发生这种情况?
似乎w3.org的这部分建议文本溢出只适用于块元素:
11.1. Overflow Ellipsis: the ‘text-overflow’ property
text-overflow clip | ellipsis | <string>
Initial: clip
APPLIES TO: BLOCK CONTAINERS <<<<
Inherited: no
Percentages: N/A
Media: visual
Computed value: as specified
MDN也是这么说的。
这个jsfiddle有您的代码(带有一些调试修改),如果它应用于div而不是td,则可以正常工作。它还有我能很快想到的唯一解决方法,即将td的内容包装在包含div的块中。然而,对我来说,这看起来像是“丑陋的”标记,所以我希望其他人有更好的解决方案。测试的代码是这样的:
td, div { overflow: hidden; text-overflow: ellipsis; white-space: nowrap; border: 1px solid red; width: 80px; } Works, but no tables anymore: <div>Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah.</div> Works, but non-semantic markup required: <table><tr><td><div>Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah.</div></td></tr></table>
如果你指定table-layout: fixed;在table元素上,那么td的样式应该生效。不过,这也会影响细胞的大小。
Sitepoint在这里稍微讨论了一下表格布局方法: http://reference.sitepoint.com/css/tableformatting
为了在文本溢出表格单元格时剪切带有省略号的文本,您需要在每个td类上设置max-width CSS属性以使溢出工作。不需要额外的布局div元素:
td
{
max-width: 100px;
overflow: hidden;
text-overflow: ellipsis;
white-space: nowrap;
}
对于响应式布局;使用max-width CSS属性来指定列的有效最小宽度,或者只使用max-width: 0;无限的灵活性。同样,包含的表需要特定的宽度,通常为width: 100%;,列的宽度通常设置为总宽度的百分比
table {width: 100%;}
td
{
max-width: 0;
overflow: hidden;
text-overflow: ellipsis;
white-space: nowrap;
}
td.column_a {width: 30%;}
td.column_b {width: 70%;}
历史:对于ie9(或更少),你需要在你的HTML中有这个,以修复特定于IE的渲染问题
<!--[if IE]>
<style>
table {table-layout: fixed; width: 100px;}
</style>
<![endif]-->
这个版本可以在IE 9中运行。

It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.</div>

指定max-width或固定宽度并不适用于所有情况,表应该是流动的,并自动为单元格设置空间。这就是桌子的作用。适用于IE9和其他浏览器。
使用这个:http://jsfiddle.net/maruxa1j/
table { width: 100%; } .first { width: 50%; } .ellipsis { position: relative; } .ellipsis:before { content: ' '; visibility: hidden; } .ellipsis span { position: absolute; left: 0; right: 0; white-space: nowrap; overflow: hidden; text-overflow: ellipsis; } <table border="1"> <thead> <tr> <th>Header 1</th> <th>Header 2</th> <th>Header 3</th> <th>Header 4</th> </tr> </thead> <tbody> <tr> <td class="ellipsis first"><span>This Text Overflows and is too large for its cell.</span></td> <td class="ellipsis"><span>This Text Overflows and is too large for its cell.</span></td> <td class="ellipsis"><span>This Text Overflows and is too large for its cell.</span></td> <td class="ellipsis"><span>This Text Overflows and is too large for its cell.</span></td> </tr> </tbody> </table>
如果你不想设置固定宽度
下面的解决方案允许您拥有较长的表单元格内容,但不能影响父表的宽度,也不能影响父行的高度。例如,你想要一个宽度为:100%的表格,但仍然对所有其他单元格应用自动调整大小的功能。在有“注释”或“评论”列的数据网格中很有用。
将这3条规则添加到你的CSS中:
.text-overflow-dynamic-container {
position: relative;
max-width: 100%;
padding: 0 !important;
display: -webkit-flex;
display: -moz-flex;
display: flex;
vertical-align: text-bottom !important;
}
.text-overflow-dynamic-ellipsis {
position: absolute;
white-space: nowrap;
overflow-y: visible;
overflow-x: hidden;
text-overflow: ellipsis;
-ms-text-overflow: ellipsis;
-o-text-overflow: ellipsis;
max-width: 100%;
min-width: 0;
width:100%;
top: 0;
left: 0;
}
.text-overflow-dynamic-container:after,
.text-overflow-dynamic-ellipsis:after {
content: '-';
display: inline;
visibility: hidden;
width: 0;
}
在任何你想要动态文本溢出的表格单元格中像这样格式化HTML:
<td>
<span class="text-overflow-dynamic-container">
<span class="text-overflow-dynamic-ellipsis" title="...your text again for usability...">
//...your long text here...
</span>
</span>
</td>
此外,对表格单元格应用所需的min-width(或根本不应用)。
当然是小提琴:https://jsfiddle.net/9wycg99v/23/
当它以表格宽度百分比为单位时,或者你不能在表格单元格上设置固定宽度。你可以应用table-layout: fixed;让它起作用。
table { table-layout: fixed; width: 100%; } td { text-overflow: ellipsis; white-space: nowrap; overflow: hidden; border: 1px solid red; } <table> <tr> <td>Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah.</td> <td>Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah.</td> </tr> </table>
如果你只是想让表格自动布局
不使用max-width,或百分比列宽度,或表布局:固定等。
https://jsfiddle.net/tturadqq/
工作原理:
步骤1:让表自动布局完成它的工作。
当有一个或多个列有很多文本时,它会尽可能地缩小其他列,然后将长列的文本换行:
步骤2:将单元格内容包装在一个div中,然后将该div设置为max-height: 1.1em
(额外的0.1em用于显示在文本底部下方的字符,如'g'和'y'的尾部)
步骤3:在divs上设置标题
这对可访问性有好处,并且对于我们稍后使用的小技巧是必要的。
第四步:在div上添加CSS::after
这是一个棘手的问题。我们使用content: attr(title)设置CSS::after,然后将其放置在div的顶部,并设置text-overflow: ellipsis。我把它涂成红色,让它更清楚。
(注意长列现在有一个尾省略号)
步骤5:设置div文本的颜色为透明
我们做完了!
在伸缩块中包装单元格内容。作为奖励,单元格自动匹配可见宽度。
table { width: 100%; } div.parent { display: flex; } div.child { flex: 1; width: 1px; overflow-x: hidden; text-overflow: ellipsis; } <table> <tr> <td> <div class="parent"> <div class="child"> xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx </div> <div> </td> </tr> </table>
我解决这个问题使用单元格内的绝对定位div(相对)。
td {
position: relative;
}
td > div {
position: absolute;
white-space: nowrap;
overflow: hidden;
text-overflow: ellipsis;
max-width: 100%;
}
就是这样。然后你可以添加一个top:值到div或垂直居中:
td > div {
top: 0;
bottom: 0;
margin: auto 0;
height: 1.5em; // = line height
}
为了在右侧获得一些空间,您可以减少max-width一点。
在我的情况下,这是有效的,在Firefox和Chrome:
td {
max-width: 0;
overflow: hidden;
text-overflow: ellipsis;
white-space: nowrap;
width: 100%;
}
这对我很管用
table {
width: 100%;
table-layout: fixed;
}
td {
text-overflow: ellipsis;
white-space: nowrap;
}
为清洁自动大小表与省略号
如果你可以抛弃表格标签,那么现代CSS有一个更干净(IMO)的解决方案:使用网格布局。
你只需要一个div或类似的东西来表示表格,里面有单元格,例如:
<div class="table">
<div class="cell">text</div>
<div class="cell">text</div>
<div class="cell">text</div>
<div class="cell">text</div>
</div>
现在,如果我想让它成为一个2x2的表格,那么它只是一个简单的例子,为网格定义两个自动大小的列:
.table {
display: grid;
grid-template-columns: auto auto;
}
对于单元格,你只需要多写几行CSS:
.cell {
text-overflow: ellipsis;
overflow: hidden;
white-space: nowrap;
}
完成工作!如果你需要确保一些列比其他列宽,那么使用fr单元或其他可用选项的列模板效果很好。
.table { 显示:网格; Grid-template-columns: auto auto; } .cell { 文本溢出:省略; 溢出:隐藏; 空白:nowrap;} 边框:1px纯黑色; } < div class = "表" > <div class="cell">long long long long long long long long long long long long long long long long long long long long long long long long long long long long long long long long long long long long long long long long long long long long long long long < div class = "单元格" >文本< / div > < div class = "单元格" >文本< / div > < div class = "单元格" >文本< / div > < / div >
XML
<td><div>Your overflowing content here.</div></td>
CSS
td div
{
max-height: 30vh;
overflow: auto;
}
为了这个特定的目的而试图打乱整个表是没有意义的。是的,有时候如果你明确不想成为另一个600个div嵌套的Twitter/Facebook“开发者”,添加一个额外的元素是可以的。
