<div class="el_table_root">
<h2>Table 表格</h2>
<h5>用于展示多条结构类似的数据,可对数据进行排序、筛选、对比或其他自定义操作。</h5>
<h3>一、基础表格</h3>
<h5>基础的表格展示用法。</h5>
<p>
当el-table元素中注入data对象数组后,在el-table-column中用prop属性来对应对象中的键名即可填入数据,用label属性来定义表格的列名。可以使用width属性来定义列宽。
</p>
<el-table :data="tableData" style="width: 100%">
<el-table-column prop="date" label="日期" width="180"></el-table-column>
<el-table-column prop="name" label="姓名" width="220"></el-table-column>
<el-table-column prop="address" label="地址"></el-table-column>
</el-table>
<h3>二、带斑马纹表格</h3>
<h5>使用带斑马纹的表格,可以更容易区分出不同行的数据。</h5>
<p>stripe属性可以创建带斑马纹的表格。它接受一个Boolean,默认为false,设置为true即为启用。</p>
<el-table
:data="tableData"
stripe
style="width: 100%">
<el-table-column
prop="date"
label="日期"
width="180">
</el-table-column>
<el-table-column
prop="name"
label="姓名"
width="180">
</el-table-column>
<el-table-column
prop="address"
label="地址">
</el-table-column>
</el-table>
<h3>三、带边框表格</h3>
<h5>默认情况下,Table
组件是不具有竖直方向的边框的,如果需要,可以使用border属性,它接受一个Boolean,设置为true即可启用。</h5>
<el-table
:data="tableData"
border
style="width: 100%">
<el-table-column
prop="date"
label="日期"
width="180">
</el-table-column>
<el-table-column
prop="name"
label="姓名"
width="180">
</el-table-column>
<el-table-column
prop="address"
label="地址">
</el-table-column>
</el-table>
<h3>四、带状态表格</h3>
<h5>可将表格内容 highlight 显示,方便区分「成功、信息、警告、危险」等内容。</h5>
<p>
可以通过指定 Table 组件的 row-class-name 属性来为 Table 中的某一行添加 class,表明该行处于某种状态。
</p>
<el-table
:data="tableData"
style="width: 100%"
:row-class-name="tableRowClassName">
<el-table-column
prop="date"
label="日期"
width="180">
</el-table-column>
<el-table-column
prop="name"
label="姓名"
width="180">
</el-table-column>
<el-table-column
prop="address"
label="地址">
</el-table-column>
</el-table>
<h3>五、固定表头</h3>
<h5>纵向内容过多时,可选择固定表头。</h5>
<p>只要在el-table元素中定义了height属性,即可实现固定表头的表格,而不需要额外的代码。</p>
<el-table
:data="tableData"
height="250"
border
style="width: 100%">
<el-table-column
prop="date"
label="日期"
width="180">
</el-table-column>
<el-table-column
prop="name"
label="姓名"
width="180">
</el-table-column>
<el-table-column
prop="address"
label="地址">
</el-table-column>
</el-table>
<h3>六、固定列</h3>
<h5>横向内容过多时,可选择固定列。</h5>
<p>固定列需要使用fixed属性,它接受 Boolean 值或者left right,表示左边固定还是右边固定。</p>
<el-table
:data="tableData"
border
style="width: 100%">
<el-table-column
fixed
prop="date"
label="日期"
width="150">
</el-table-column>
<el-table-column
prop="name"
label="姓名"
width="120">
</el-table-column>
<el-table-column
prop="province"
label="省份"
width="120">
</el-table-column>
<el-table-column
prop="city"
label="市区"
width="120">
</el-table-column>
<el-table-column
prop="address"
label="地址"
width="300">
</el-table-column>
<el-table-column
prop="zip"
label="邮编"
width="120">
</el-table-column>
<el-table-column
fixed="right"
label="操作"
width="100">
<template slot-scope="scope">
<el-button @click="handleClick(scope.row)" type="text" size="small">查看</el-button>
<el-button type="text" size="small">编辑</el-button>
</template>
</el-table-column>
</el-table>
<h3>七、固定列和表头</h3>
<h5>横纵内容过多时,可选择固定列和表头。</h5>
<p>固定列和表头可以同时使用,只需要将上述两个属性分别设置好即可。</p>
<el-table
:data="tableData"
style="width: 100%"
height="250">
<el-table-column
fixed
prop="date"
label="日期"
width="150">
</el-table-column>
<el-table-column
prop="name"
label="姓名"
width="120">
</el-table-column>
<el-table-column
prop="province"
label="省份"
width="120">
</el-table-column>
<el-table-column
prop="city"
label="市区"
width="120">
</el-table-column>
<el-table-column
prop="address"
label="地址"
width="300">
</el-table-column>
<el-table-column
prop="zip"
label="邮编"
width="120">
</el-table-column>
</el-table>
<h3>八、流体高度</h3>
<h5>当数据量动态变化时,可以为 Table 设置一个最大高度。</h5>
<p>通过设置max-height属性为 Table 指定最大高度。此时若表格所需的高度大于最大高度,则会显示一个滚动条。</p>
<el-table
:data="tableData"
style="width: 100%"
max-height="250">
<el-table-column
fixed
prop="date"
label="日期"
width="150">
</el-table-column>
<el-table-column
prop="name"
label="姓名"
width="120">
</el-table-column>
<el-table-column
prop="province"
label="省份"
width="120">
</el-table-column>
<el-table-column
prop="city"
label="市区"
width="120">
</el-table-column>
<el-table-column
prop="address"
label="地址"
width="300">
</el-table-column>
<el-table-column
prop="zip"
label="邮编"
width="120">
</el-table-column>
<el-table-column
fixed="right"
label="操作"
width="120">
<template slot-scope="scope">
<el-button
@click.native.prevent="deleteRow(scope.$index, tableData)"
type="text"
size="small">
移除
</el-button>
</template>
</el-table-column>
</el-table>
<h3>九、多级表头</h3>
<h5>数据结构比较复杂的时候,可使用多级表头来展现数据的层次关系。</h5>
<p>只需要在 el-table-column 里面嵌套 el-table-column,就可以实现多级表头。</p>
<el-table
:data="tableData"
style="width: 100%">
<el-table-column
prop="date"
label="日期"
width="150">
</el-table-column>
<el-table-column label="配送信息">
<el-table-column
prop="name"
label="姓名"
width="120">
</el-table-column>
<el-table-column label="地址">
<el-table-column
prop="province"
label="省份"
width="120">
</el-table-column>
<el-table-column
prop="city"
label="市区"
width="120">
</el-table-column>
<el-table-column
prop="address"
label="地址"
width="300">
</el-table-column>
<el-table-column
prop="zip"
label="邮编"
width="120">
</el-table-column>
</el-table-column>
</el-table-column>
</el-table>
<h3>十、单选</h3>
<h5>选择单行数据时使用色块表示。</h5>
<p>
Table
组件提供了单选的支持,只需要配置highlight-current-row属性即可实现单选。之后由current-change事件来管理选中时触发的事件,它会传入currentRow,oldCurrentRow。如果需要显示索引,可以增加一列el-table-column,设置type属性为index即可显示从
1 开始的索引号。
</p>
<el-table
ref="singleTable"
:data="tableData"
highlight-current-row
@current-change="handleCurrentChange"
style="width: 100%">
<el-table-column
type="index"
width="50">
</el-table-column>
<el-table-column
property="date"
label="日期"
width="120">
</el-table-column>
<el-table-column
property="name"
label="姓名"
width="120">
</el-table-column>
<el-table-column
property="address"
label="地址">
</el-table-column>
</el-table>
<div style="margin-top: 20px">
<el-button @click="setCurrent(tableData[1])">选中第二行</el-button>
<el-button @click="setCurrent()">取消选择</el-button>
</div>
<h3>十一、多选</h3>
<h5>选择多行数据时使用 Checkbox。</h5>
<p>实现多选非常简单: 手动添加一个el-table-column,设type属性为selection即可;默认情况下若内容过多会折行显示,
若需要单行显示可以使用show-overflow-tooltip属性,它接受一个Boolean,为true时多余的内容会在 hover 时以 tooltip 的形式显示出来。
</p>
<el-table
ref="multipleTable"
:data="tableData"
tooltip-effect="dark"
style="width: 100%"
@selection-change="handleSelectionChange">
<el-table-column
type="selection"
width="55">
</el-table-column>
<el-table-column
label="日期"
width="120">
<template slot-scope="scope">{{ scope.row.date }}</template>
</el-table-column>
<el-table-column
prop="name"
label="姓名"
width="120">
</el-table-column>
<el-table-column
prop="address"
label="地址"
show-overflow-tooltip>
</el-table-column>
</el-table>
<div style="margin-top: 20px">
<el-button @click="toggleSelection([tableData[1], tableData[2]])">切换第二、第三行的选中状态</el-button>
<el-button @click="toggleSelection()">取消选择</el-button>
</div>
<h3>十二、排序</h3>
<h5>对表格进行排序,可快速查找或对比数据。</h5>
<p>
在列中设置sortable属性即可实现以该列为基准的排序,接受一个Boolean,默认为false。可以通过 Table 的default-sort属性设置默认的排序列和排序顺序。
可以使用sort-method或者sort-by使用自定义的排序规则。如果需要后端排序,需将sortable设置为custom,同时在 Table 上监听sort-change事件,
在事件回调中可以获取当前排序的字段名和排序顺序,从而向接口请求排序后的表格数据。在本例中,我们还使用了formatter属性,它用于格式化指定列的值,
接受一个Function,会传入两个参数:row和column,可以根据自己的需求进行处理。
</p>
<el-table
:data="tableData"
style="width: 100%"
:default-sort = "{prop: 'date', order: 'descending'}"
>
<el-table-column
prop="date"
label="日期"
sortable
width="180">
</el-table-column>
<el-table-column
prop="name"
label="姓名"
sortable
width="180">
</el-table-column>
<el-table-column
prop="address"
label="地址"
:formatter="formatter">
</el-table-column>
</el-table>
<h3>十三、筛选</h3>
<h5>对表格进行筛选,可快速查找到自己想看的数据。</h5>
<p>在列中设置filtersfilter-method属性即可开启该列的筛选,filters 是一个数组,filter-method是一个方法,
它用于决定某些数据是否显示,会传入三个参数:value, row 和 column。
</p>
<el-button @click="resetDateFilter">清除日期过滤器</el-button>
<el-button @click="clearFilter">清除所有过滤器</el-button>
<el-table
ref="filterTable"
:data="tableData2"
style="width: 100%">
<el-table-column
prop="date"
label="日期"
sortable
width="180"
column-key="date"
:filters="[{text: '2016-05-01', value: '2016-05-01'}, {text: '2016-05-02', value: '2016-05-02'}, {text: '2016-05-03', value: '2016-05-03'}, {text: '2016-05-04', value: '2016-05-04'}]"
:filter-method="filterHandler"
>
</el-table-column>
<el-table-column
prop="name"
label="姓名"
width="180">
</el-table-column>
<el-table-column
prop="address"
label="地址"
:formatter="formatter">
</el-table-column>
<el-table-column
prop="tag"
label="标签"
width="100"
:filters="[{ text: '家', value: '家' }, { text: '公司', value: '公司' }]"
:filter-method="filterTag"
filter-placement="bottom-end">
<template slot-scope="scope">
<el-tag
:type="scope.row.tag === '家' ? 'primary' : 'success'"
disable-transitions>{{scope.row.tag}}</el-tag>
</template>
</el-table-column>
</el-table>
<h3>十四、自定义列模板</h3>
<h5>自定义列的显示内容,可组合其他组件使用。</h5>
<p>通过 Scoped slot 可以获取到 row, column, $index 和 store(table 内部的状态管理)的数据,用法参考 demo。</p>
<el-table
:data="tableData"
style="width: 100%">
<el-table-column
label="日期"
width="180">
<template slot-scope="scope">
<i class="el-icon-time"></i>
<span style="margin-left: 10px">{{ scope.row.date }}</span>
</template>
</el-table-column>
<el-table-column
label="姓名"
width="180">
<template slot-scope="scope">
<el-popover trigger="hover" placement="top">
<p>姓名: {{ scope.row.name }}</p>
<p>住址: {{ scope.row.address }}</p>
<div slot="reference" class="name-wrapper">
<el-tag size="medium">{{ scope.row.name }}</el-tag>
</div>
</el-popover>
</template>
</el-table-column>
<el-table-column label="操作">
<template slot-scope="scope">
<el-button
size="mini"
@click="handleEdit(scope.$index, scope.row)">编辑</el-button>
<el-button
size="mini"
type="danger"
@click="handleDelete(scope.$index, scope.row)">删除</el-button>
</template>
</el-table-column>
</el-table>
<h3>十五、展开行</h3>
<h5>当行内容过多并且不想显示横向滚动条时,可以使用 Table 展开行功能。</h5>
<p>通过设置 type="expand" 和 Scoped slot 可以开启展开行功能,el-table-column 的模板会被渲染成为展开行的内容,
展开行可访问的属性与使用自定义列模板时的 Scoped slot 相同。
</p>
<el-table
:data="tableData3"
style="width: 100%">
<el-table-column type="expand">
<template slot-scope="props">
<el-form label-position="left" inline class="demo-table-expand">
<el-form-item label="商品名称">
<span>{{ props.row.name }}</span>
</el-form-item>
<el-form-item label="所属店铺">
<span>{{ props.row.shop }}</span>

<h3>十六、树形数据与懒加载</h3>
<h5>
支持树类型的数据的显示。当 row 中包含 children 字段时,被视为树形数据。渲染树形数据时,必须要指定 row-key。支持子节点数据异步加载。
设置 Table 的 lazy 属性为 true 与加载函数 load 。通过指定 row 中的 hasChildren 字段来指定哪些行是包含子节点。
children 与 hasChildren 都可以通过 tree-props 配置。
</h5>
<el-table
:data="tableData0"
style="width: 100%;margin-bottom: 20px;"
row-key="id"
border
default-expand-all
:tree-props="{children: 'children', hasChildren: 'hasChildren'}">
<el-table-column
prop="date"
label="日期"
sortable
width="180">
</el-table-column>
<el-table-column
prop="name"
label="姓名"
sortable
width="180">
</el-table-column>
<el-table-column
prop="address"
label="地址">
</el-table-column>
</el-table>
<el-table
:data="tableData1"
style="width: 100%"
row-key="id"
border
lazy
:load="load"
:tree-props="{children: 'children', hasChildren: 'hasChildren'}">
<el-table-column
prop="date"
label="日期"
width="180">
</el-table-column>
<el-table-column
prop="name"
label="姓名"
width="180">
</el-table-column>
<el-table-column
prop="address"
label="地址">
</el-table-column>
</el-table>
<h3>十七、自定义表头</h3>
<h5>表头支持自定义。通过设置 Scoped slot 来自定义表头。</h5>
<el-table
:data="tableData.filter(data => !search || data.name.toLowerCase().includes(search.toLowerCase()))"
style="width: 100%">
<el-table-column
label="Date"
prop="date">
</el-table-column>
<el-table-column
label="Name"
prop="name">
</el-table-column>
<el-table-column
align="right">
<template slot="header" slot-scope="scope">
<el-input
v-model="search"
size="mini"
placeholder="输入关键字搜索"/>
</template>
<template slot-scope="scope">
<el-button
size="mini"
@click="handleEdit(scope.$index, scope.row)">Edit</el-button>
<el-button
size="mini"
type="danger"
@click="handleDelete(scope.$index, scope.row)">Delete</el-button>
</template>
</el-table-column>
</el-table>
<h3>十八、表尾合计行</h3>
<h5>若表格展示的是各类数字,可以在表尾显示各列的合计。</h5>
<p>
将show-summary设置为true就会在表格尾部展示合计行。默认情况下,对于合计行,第一列不进行数据求合操作,而是显示「合计」二字(可通过sum-text配置),
其余列会将本列所有数值进行求合操作,并显示出来。当然,你也可以定义自己的合计逻辑。使用summary-method并传入一个方法,
返回一个数组,这个数组中的各项就会显示在合计行的各列中,具体可以参考本例中的第二个表格。
</p>
<el-table
:data="tableData4"
border
show-summary
style="width: 100%">
<el-table-column
prop="id"
label="ID"
width="180">
</el-table-column>
<el-table-column
prop="name"
label="姓名">
</el-table-column>
<el-table-column
prop="amount1"
sortable
label="数值 1">
</el-table-column>
<el-table-column
prop="amount2"
sortable
label="数值 2">
</el-table-column>
<el-table-column
prop="amount3"
sortable
label="数值 3">
</el-table-column>
</el-table>
<el-table
:data="tableData4"
border
height="200"
:summary-method="getSummaries"
show-summary
style="width: 100%; margin-top: 20px">
<el-table-column
prop="id"
label="ID"
width="180">
</el-table-column>
<el-table-column
prop="name"
label="姓名">
</el-table-column>
<el-table-column
prop="amount1"
label="数值 1(元)">
</el-table-column>
<el-table-column
prop="amount2"
label="数值 2(元)">
</el-table-column>
<el-table-column
prop="amount3"
label="数值 3(元)">
</el-table-column>
</el-table>
<h3>十九、合并行或列</h3>
<h5>多行或多列共用一个数据时,可以合并行或列。</h5>
<p>
通过给table传入span-method方法可以实现合并行或列,方法的参数是一个对象,里面包含当前行row、当前列column、当前行号rowIndex、当前列号columnIndex四个属性。
该函数可以返回一个包含两个元素的数组,第一个元素代表rowspan,第二个元素代表colspan。 也可以返回一个键名为rowspan和colspan的对象。
</p>
<el-table
:data="tableData4"
:span-method="arraySpanMethod"
border
style="width: 100%">
<el-table-column
prop="id"
label="ID"
width="180">
</el-table-column>
<el-table-column
prop="name"
label="姓名">
</el-table-column>
<el-table-column
prop="amount1"
sortable
label="数值 1">
</el-table-column>
<el-table-column
prop="amount2"
sortable
label="数值 2">
</el-table-column>
<el-table-column
prop="amount3"
sortable
label="数值 3">
</el-table-column>
</el-table>
<el-table
:data="tableData4"
:span-method="objectSpanMethod"
border
style="width: 100%; margin-top: 20px">
<el-table-column
prop="id"
label="ID"
width="180">
</el-table-column>
<el-table-column
prop="name"
label="姓名">
</el-table-column>
<el-table-column
prop="amount1"
label="数值 1(元)">
</el-table-column>
<el-table-column
prop="amount2"
label="数值 2(元)">
</el-table-column>
<el-table-column
prop="amount3"
label="数值 3(元)">
</el-table-column>
</el-table>
<h3>二十、自定义索引</h3>
<h5>自定义 type=index 列的行号。</h5>
<p>
通过给 type=index 的列传入 index 属性,可以自定义索引。该属性传入数字时,将作为索引的起始值。也可以传入一个方法,
它提供当前行的行号(从 0 开始)作为参数,返回值将作为索引展示。
</p>
<el-table
:data="tableData5"
style="width: 100%">
<el-table-column
type="index"
:index="indexMethod">
</el-table-column>
<el-table-column
prop="date"
label="日期"
width="180">
</el-table-column>
<el-table-column
prop="name"
label="姓名"
width="180">
</el-table-column>
<el-table-column
prop="address"
label="地址">
</el-table-column>
</el-table>
