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:
<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>
上面代码中给table元素添加 table-layout: fixed; 或者给td添加 word-break: break-all ,都可以达到表格安装我们设置的宽度显示:
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:
<p style="margin-bottom: 7px;"><style><br/> *{padding:0;margin:0;font-size: 12px;color: #333}<br/> li{<a href="http://www.php.cn/wiki/953.html" target="_blank">list-style</a>: none;}<br/><br/> table{border:2px solid #ccc;width: 100%;text-align: center;border-collapse:collapse;}<br/> td,th{height: 30px;border:2px solid #ccc;word-break: break-all;}<br/><br/> .ellipsis{white-space: nowrap; overflow: hidden; text-overflow: ellipsis;}<br/></style><br/><br/><table width="400" border="1" id="table1"><br/> <tr><br/> <td>3</td><br/> <td class="ellipsis" width="10%">aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa</td><br/> <td width="40%">5</td><br/> </tr><br/> <tr><br/> <td>3</td><br/> <td>4</td><br/> <td>5</td><br/> </tr><br/></table><br/></p>
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:
上面代码均兼容ie6+
