element-ui el-table表格固定表头代码示例
作者：薛小胖And汤小懒
Element-UI的el-table组件是一个非常强大的表格组件,它提供了多种常见的表格功能,如排序、筛选、分页、自定义列模板等,这篇文章主要给大家介绍了关于element-ui el-table表格固定表头的相关资料,需要的朋友可以参考下
前提：table内容过高时页面滚动到下方后，表头看不见无法明确各列的含义
1. 官网给出两种种属性来固定表头 height 以及 max-height；但是有个问题就是 height高度会被定死，max-height无法适应不同分辨率的情况
<el-table ref="multipleTable" :data="listData" height="200" class="img-tab">
<el-table-column label="序号" prop="pagingCustomOrder" align="center" width="80" />
<el-table-column align="center" label="报警时间" prop="warningTime" />
<el-table-column align="center" label="企业名称" prop="companyName" />
</el-table><el-table ref="multipleTable" :data="listData" max-height="200" class="img-tab">
<el-table-column label="序号" prop="pagingCustomOrder" align="center" width="80" />
<el-table-column align="center" label="报警时间" prop="warningTime" />
<el-table-column align="center" label="企业名称" prop="companyName" />
</el-table>2. 可以进行样式控制表格高度，达到固定表头的需求，就可以避免高度定死的情况
<el-table ref="multipleTable" :data="listData" class="scroll-tab">
<el-table-column label="序号" prop="pagingCustomOrder" align="center" width="80" />
<el-table-column align="center" label="报警时间" prop="warningTime" />
<el-table-column align="center" label="企业名称" prop="companyName" />
</el-table>// table表头固定
.el-table.scroll-tab {
overflow: auto;
max-height: calc(100% - 200px);
}
.scroll-tab .el-table__header-wrapper {
position: sticky;
top: 0;//这个值根据实际情况而定
z-index: 10;
}3. 若是表格宽度也超出内容，需要横向滚动+竖向滚动
// table表头固定
.el-table.scroll-tab {
overflow: hidden;
height: calc(100% - 200px);
}
.scroll-tab .el-table__header-wrapper {
position: sticky;
top: 0;//这个值根据实际情况而定
z-index: 10;
}
.scroll-tab .el-table__body-wrapper {
height: calc(100% - 60px);
overflow: auto;
}附：el-table固定表头（设置height）出现内容过多时不能滚动问题
主要原因是el-table没有div包裹
解决：加一个div并设置其高度和overflow
我自己的主要代码
<div class="contentTable">
<el-table
ref="table"
:data="tableData"
stripe
@row-dblclick="onRowDblclick"
height="100%"
>
<el-table-column
type="index"
align="center"
label="序号"
width="50"
></el-table-column>
<el-table-column
prop="templateName"
align="center"
label="模板名称"
width="150"
></el-table-column>
<el-table-column
prop="mainContent"
align="center"
label="主要内容"
></el-table-column>
<el-table-column
prop="devContent"
align="center"
label="活动措施和设备状态"
></el-table-column>
<el-table-column prop="operate" align="center" label="操作" width="80">
<template slot-scope="scope">
<el-button
size="mini"
class="delete-btn"
@click="onDelete(scope.row)"
title="删除"
v-isLogin
></el-button>
</template>
</el-table-column>
</el-table>
</div>css代码：
.contentTable {
height: calc(100% - 50px) !important;
overflow: scroll;
}
.contentTable >>> .el-table__body-wrapper::-webkit-scrollbar {
width: 10px;
height: 8px;
}-webkit-scrollbar用来加滚动条的！！！
页面所有代码：
<template>
<el-dialog
:title="title"
:visible.sync="visible"
class="template-query"
@opened="openInit"
append-to-body
width="80%"
>
<el-form
:model="form"
ref="form"
:inline="true"
style="text-align: right"
size="small"
>
<el-form-item label="模板名称：" prop="templateName">
<el-input
v-model="form.templateName"
maxlength="20"
v-special-code
></el-input>
</el-form-item>
<el-form-item>
<el-button type="primary" @click="onQuery">查询</el-button>
<el-button type="primary" @click="onReset">重置</el-button>
</el-form-item>
</el-form>
<div class="contentTable">
<el-table
ref="table"
