应用场景一:
当表格中有很长的英文时,如果没有设置table-layout:fixed 或者 word-break:break-all,则单元格显示的宽度不是我们设置的宽度,如下:
<!DOCTYPE html> <html> <head> <meta charset="utf-8" /> <meta name="viewport" content="width=device-width, initial-scale=1"> <title></title> </head> <body> <style> table { border: 2px solid #ccc; width: 100%; text-align: center; border-collapse: collapse; /*table-layout: fixed;*/ } td,th { height: 30px; border: 2px solid #ccc; /*word-break: break-all;*/ } </style> <table width="400" border="1" id="table1"> <tr> <td>3</td> <td width="10%">aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa</td> <td width="20%">aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa</td> </tr> <tr> <td>3</td> <td>4</td> <td>5</td> </tr> </table> </body> </html>
table{border:2px solid #ccc;width: 100%;text-align: center;border-collapse:collapse;table-layout: fixed;} td,th{height: 30px;border:2px solid #ccc;/*word-break: break-all;*/}
table{border:2px solid #ccc;width: 100%;text-align: center;border-collapse:collapse;/*table-layout: fixed;*/} td,th{height: 30px;border:2px solid #ccc;word-break: break-all;}
应用场景二:
css的省略号的一般写法:
white-space: nowrap; overflow: hidden; text-overflow: ellipsis;
当你想在table中应用省略号:
<style>
* {
padding: 0;
margin: 0;
font-size: 12px;
color: #333
}
li {
list-style: none;
}
table {
border: 2px solid #ccc;
width: 100%;
text-align: center;
border-collapse: collapse;
}
td,
th {
height: 30px;
border: 2px solid #ccc;
word-break: break-all;
}
.ellipsis {
white-space: nowrap;
overflow: hidden;
text-overflow: ellipsis;
}
</style>
<table width="400" border="1" id="table1">
<tr>
<td>3</td>
<td class="ellipsis" width="10%">aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa</td>
<td width="40%">5</td>
</tr>
<tr>
<td>3</td>
<td>4</td>
<td>5</td>
</tr>
</table>
结果完全不是我们想要的:
解决方法:添加 table-layout: fixed;
<style>
* {
padding: 0;
margin: 0;
font-size: 12px;
color: #333
}
li {
list-style: none;
}
table {
border: 2px solid #ccc;
width: 100%;
text-align: center;
border-collapse: collapse;
table-layout: fixed;
}
td,
th {
height: 30px;
border: 2px solid #ccc;
word-break: break-all;
}
.ellipsis {
white-space: nowrap;
overflow: hidden;
text-overflow: ellipsis;
}
</style>
<table width="400" border="1" id="table1">
<tr>
<td>3</td>
<td class="ellipsis" width="10%">aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa</td>
<td width="40%">5</td>
</tr>
<tr>
<td>3</td>
<td>4</td>
<td>5</td>
</tr>
</table>
效果完全是我们想要的:
