## Table 表格
|
||
|
||
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。
|
||
|
||
### 基础表格
|
||
|
||
基础的表格展示用法。
|
||
|
||
:::demo 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。
|
||
```html
|
||
<template>
|
||
<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="180">
|
||
</el-table-column>
|
||
<el-table-column
|
||
prop="address"
|
||
label="地址">
|
||
</el-table-column>
|
||
</el-table>
|
||
</template>
|
||
|
||
<script>
|
||
export default {
|
||
data() {
|
||
return {
|
||
tableData: [{
|
||
date: '2016-05-02',
|
||
name: '王小虎',
|
||
address: '上海市普陀区金沙江路 1518 弄'
|
||
}, {
|
||
date: '2016-05-04',
|
||
name: '王小虎',
|
||
address: '上海市普陀区金沙江路 1517 弄'
|
||
}, {
|
||
date: '2016-05-01',
|
||
name: '王小虎',
|
||
address: '上海市普陀区金沙江路 1519 弄'
|
||
}, {
|
||
date: '2016-05-03',
|
||
name: '王小虎',
|
||
address: '上海市普陀区金沙江路 1516 弄'
|
||
}]
|
||
}
|
||
}
|
||
}
|
||
</script>
|
||
```

### 带斑马纹表格
|
||
|
||
使用带斑马纹的表格，可以更容易区分出不同行的数据。
|
||
|
||
:::demo `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。
|
||
```html
|
||
<template>
|
||
<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>
|
||
</template>
|
||
|
||
<script>
|
||
export default {
|
||
data() {
|
||
return {
|
||
tableData: [{
|
||
date: '2016-05-02',
|
||
name: '王小虎',
|
||
address: '上海市普陀区金沙江路 1518 弄'
|
||
}, {
|
||
date: '2016-05-04',
|
||
name: '王小虎',
|
||
address: '上海市普陀区金沙江路 1517 弄'
|
||
}, {
|
||
date: '2016-05-01',
|
||
name: '王小虎',
|
||
address: '上海市普陀区金沙江路 1519 弄'
|
||
}, {
|
||
date: '2016-05-03',
|
||
name: '王小虎',
|
||
address: '上海市普陀区金沙江路 1516 弄'
|
||
}]
|
||
}
|
||
}
|
||
}
|
||
</script>
|
||
```
|
||
:::
|
||
|
||
### 带边框表格
|
||
|
||
:::demo 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。
|
||
```html
|
||
<template>
|
||
<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>
|
||
</template>
|
||
|
||
<script>
|
||
export default {
|
||
data() {
|
||
return {
|
||
tableData: [{
|
||
date: '2016-05-02',
|
||
name: '王小虎',
|
||
address: '上海市普陀区金沙江路 1518 弄'
|
||
}, {
|
||
date: '2016-05-04',
|
||
name: '王小虎',
|
||
address: '上海市普陀区金沙江路 1517 弄'
|
||
}, {
|
||
date: '2016-05-01',
|
||
name: '王小虎',
|
||
address: '上海市普陀区金沙江路 1519 弄'
|
||
}, {
|
||
date: '2016-05-03',
|
||
name: '王小虎',
|
||
address: '上海市普陀区金沙江路 1516 弄'
|
||
}]
|
||
}
|
||
}
|
||
}
|
||
</script>
|
||
```
|
||
:::
|
||
|
||
### 带状态表格
|
||
|
||
可将表格内容 highlight 显示，方便区分「成功、信息、警告、危险」等内容。
|
||
|
||
:::demo 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。
|
||
```html
|
||
<template>
|
||
<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>
|
||
</template>
|
||
|
||
<style>
|
||
.el-table .warning-row {
|
||
background: oldlace;
|
||
}
|
||
|
||
.el-table .success-row {
|
||
background: #f0f9eb;
|
||
}
|
||
</style>
|
||
|
||
<script>
|
||
export default {
|
||
methods: {
|
||
tableRowClassName({row, rowIndex}) {
|
||
if (rowIndex === 1) {
|
||
return 'warning-row';
|
||
} else if (rowIndex === 3) {
|
||
return 'success-row';
|
||
}
|
||
return '';
|
||
}
|
||
},
|
||
data() {
|
||
return {
|
||
tableData: [{
|
||
date: '2016-05-02',
|
||
name: '王小虎',
|
||
address: '上海市普陀区金沙江路 1518 弄',
|
||
}, {
|
||
date: '2016-05-04',

|
||
}, {
|
||
date: '2016-05-03',
|
||
name: '王小虎',
|
||
address: '上海市普陀区金沙江路 1518 弄'
|
||
}]
|
||
}
|
||
}
|
||
}
|
||
</script>
|
||
```
|
||
:::
|
||
|
||
### 固定表头
|
||
|
||
纵向内容过多时，可选择固定表头。
|
||
|
||
:::demo 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。
|
||
```html
|
||
<template>
|
||
<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>
|

</template>
|

<script>
|

export default {

data() {

:::
|
||
|
||
### 固定列
|
||
|
||
横向内容过多时，可选择固定列。
|
||
|
||
:::demo 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。
|
||
```html

### 固定列和表头

### 流体高度
|
||
|
||
当数据量动态变化时，可以为 Table 设置一个最大高度。
|
||
|
||
:::demo 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。

### 多级表头
|
||
|
||
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。
|
||
|
||
:::demo 只需要在 el-table-column 里面嵌套 el-table-column，就可以实现多级表头。
|
||

### 单选
|
||
|
||
选择单行数据时使用色块表示。
|
||
|
||
:::demo 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。
|
||
```html
|
||
<template>
|
||
<el-table
|
||
ref="singleTable"
|
||
:data="tableData"
|
||
highlight-current-row
|
||
@current-change="handleCurrentChange"
|
||
style="width: 100%">
|
||
<el-table-column
|
||
type="index"
|
||

|
||
</el-table-column>
|
||
<el-table-column
|
||
property="date"
|
||
label="日期"
|
||
width="120">

|
||
<div style="margin-top: 20px">
|
||
<el-button @click="setCurrent(tableData[1])">选中第二行</el-button>

### 多选
|
||
|
||
选择多行数据时使用 Checkbox。
|
||
|
||
:::demo 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。
|
||
```html
|
||
<template>
|
||
<el-table
|
||
ref="multipleTable"
|
||
:data="tableData"
|
||
tooltip-effect="dark"
|
||
style="width: 100%"
|
||
@selection-change="handleSelectionChange">
|
||
<el-table-column
|
||

### 排序
|
||
|
||
对表格进行排序，可快速查找或对比数据。
|
||
|
||
:::demo 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。
|
||
```html
|
||
<template>
|
||
<el-table

### 筛选
|
||
|
||
对表格进行筛选，可快速查找到自己想看的数据。
|
||
|
||
:::demo 在列中设置`filters` `filter-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`。
|
||
```html
|
||
<template>
|
||
<el-button @click="resetDateFilter">清除日期过滤器</el-button>
|

### 展开行
|
||
|
||
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。
|
||
:::demo 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。

### 树形数据与懒加载
|
||
|
||
:::demo 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。

### 表尾合计行
|
||
|
||
若表格展示的是各类数字，可以在表尾显示各列的合计。
|
||
:::demo 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。

### 合并行或列
|
||
|
||
多行或多列共用一个数据时，可以合并行或列。
|
||
:::demo 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。

### 自定义索引
|
||
|
||
自定义 `type=index` 列的行号。
|
||
:::demo 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。
