查了挺多方法,都是写了两个表格来实现,表头一个table 内容一个table。但是页面都写好了不想改,就直接自己用css进行了控制。弊端:不方便适用于多个页面。因为th td的宽度需要固定住。不固定就直接把屏幕宽度等分了。所以,一些内容较多的列需要手动控制宽度。直接上代码,因公司项目,所以。。
<div>
<div class="table-head">
<table id="contentTable">
<thead>
<tr>
<th><input type="checkbox"/></th>
<th>xxxxx</th>
<th>xxxxx</th>
<th>证件号码</th>
<th>姓名</th>
<th>性别</th>
<th>xxxxx</th>
<th>出生日期</th>
<th>xxx</th>
<th>xxx</th>
<th>ssss</th>
<th>xxxx</th>
<th>ccccc手机</th>
<th>家庭住址</th>
<th>xxxxx</th>
<th>xxxxx</th>
<th>xxxxx</th>
<th>修改日期</th>
</tr>
</thead>
<tbody>
<tr>
//18个td 省略
</tr>
</tbody>
</table>
</div>
</div>
/** 这是css */
body{overflow-y: hidden}
#contentTable tbody { display: block; height: 520px; overflow-y: scroll; }
#contentTable thead,
#contentTable tbody tr { display: table; width: 100%; table-layout: fixed; /**表格列的宽度由表格宽度决定,不由内容决定*/ text-align: center; }
/**每一个th都要和对应的td宽度相同,如果不设置,则默认均分宽度,我设置的都是一些内容较多的,比如说身份证号码,电话,住址等*/
#contentTable tr th:nth-of-type(1),#contentTable tr td:nth-of-type(1){width: 1.5%;}
#contentTable tr th:nth-of-type(2),#contentTable tr td:nth-of-type(2){width: 8.5%;}
#contentTable tr th:nth-of-type(3),#contentTable tr td:nth-of-type(3){width: 7%;}
#contentTable tr th:nth-of-type(4),#contentTable tr td:nth-of-type(4){width: 8.5%;}
#contentTable tr th:nth-of-type(8),#contentTable tr td:nth-of-type(8){width: 5%;}
#contentTable tr th:nth-of-type(9),#contentTable tr td:nth-of-type(9){width: 5%;}
#contentTable tr th:nth-of-type(12),#contentTable tr td:nth-of-type(12){width: 8.5%;}
#contentTable tr th:nth-of-type(13),#contentTable tr td:nth-of-type(13){width: 6%;}
#contentTable tr th:nth-of-type(14),#contentTable tr td:nth-of-type(14){width: 15%;}
#contentTable tr th:nth-of-type(16),#contentTable tr td:nth-of-type(16){width: 5%;}
#contentTable tr th:nth-of-type(18),#contentTable tr td:nth-of-type(18){width: 5%;}
/**这一个重要:写完上面的看效果应该是表头和内容对不齐。我们需要的是调节0.4em中的0.4,试着变大变小就能看到区别,我试了,刚好跳到0.4,所有的列都能垂直对齐*/
#contentTable thead { width: calc( 100% - 0.4em);/*表头与表格垂直对齐*/ }
