## Table

Display multiple data with similar format. You can sort, filter, compare your data in a table.

### Basic table

Basic table is just for data display.

:::demo After setting attribute `data` of `el-table` with an object array, you can use `prop` (corresponding to a key of the object in `data` array) in `el-table-column` to insert data to table columns, and set the attribute `label` to define the column name. You can also use the attribute `width` to define the width of columns.

```html
  <template>
    <el-table
      :data="tableData"
      style="width: 100%">
      <el-table-column
        prop="date"
        label="Date"
        width="180">
      </el-table-column>
      <el-table-column
        prop="name"
        label="Name"
        width="180">
      </el-table-column>
      <el-table-column
        prop="address"
        label="Address">
      </el-table-column>
    </el-table>
  </template>

  <script>
    export default {
      data() {
        return {
          tableData: [{
            date: '2016-05-03',
            name: 'Tom',
            address: 'No. 189, Grove St, Los Angeles'
          }, {
            date: '2016-05-02',
            name: 'Tom',
            address: 'No. 189, Grove St, Los Angeles'
          }, {
            date: '2016-05-04',
            name: 'Tom',
            address: 'No. 189, Grove St, Los Angeles'
          }, {
            date: '2016-05-01',
            name: 'Tom',
            address: 'No. 189, Grove St, Los Angeles'
          }]
        }
      }
    }
  </script>
```
:::

### Striped Table

Striped table makes it easier to distinguish different rows.

:::demo Attribute `stripe` accepts a `Boolean`. If `true`, table will be striped.
```html
<template>
  <el-table
    :data="tableData"
    stripe
    style="width: 100%">
    <el-table-column
      prop="date"
      label="Date"
      width="180">
    </el-table-column>
    <el-table-column
      prop="name"
      label="Name"
      width="180">
    </el-table-column>
    <el-table-column
      prop="address"
      label="Address">
    </el-table-column>
  </el-table>
</template>

<script>
  export default {
    data() {
      return {
        tableData: [{
          date: '2016-05-03',
          name: 'Tom',
          address: 'No. 189, Grove St, Los Angeles'
        }, {
          date: '2016-05-02',
          name: 'Tom',
          address: 'No. 189, Grove St, Los Angeles'
        }, {
          date: '2016-05-04',
          name: 'Tom',
          address: 'No. 189, Grove St, Los Angeles'
        }, {
          date: '2016-05-01',
          name: 'Tom',
          address: 'No. 189, Grove St, Los Angeles'
        }]
      }
    }
  }
</script>
```
:::

### Table with border

:::demo By default, Table has no vertical border. If you need it, you can set attribute `border` to `true`.

```html
<template>
  <el-table
    :data="tableData"
    border
    style="width: 100%">
    <el-table-column
      prop="date"
      label="Date"
      width="180">
    </el-table-column>
    <el-table-column
      prop="name"
      label="Name"
      width="180">
    </el-table-column>
    <el-table-column
      prop="address"
      label="Address">
    </el-table-column>
  </el-table>
</template>

<script>
  export default {
    data() {
      return {
        tableData: [{
          date: '2016-05-03',
          name: 'Tom',
          address: 'No. 189, Grove St, Los Angeles'
        }, {
          date: '2016-05-02',
          name: 'Tom',
          address: 'No. 189, Grove St, Los Angeles'
        }, {
          date: '2016-05-04',
          name: 'Tom',
          address: 'No. 189, Grove St, Los Angeles'
        }, {
          date: '2016-05-01',
          name: 'Tom',
          address: 'No. 189, Grove St, Los Angeles'
        }]
      }
    }
  }
</script>
```
:::

### Table with status

You can highlight your table content to distinguish between "success, information, warning, danger" and other states.

:::demo Use `row-class-name` in `el-table` to add custom classes to a certain row. Then you can style it with custom classes.
```html
<template>
  <el-table
    :data="tableData2"
    style="width: 100%"
    :row-class-name="tableRowClassName">
    <el-table-column
      prop="date"
      label="Date"
      width="180">
    </el-table-column>
    <el-table-column
      prop="name"
      label="Name"
      width="180">
    </el-table-column>
    <el-table-column
      prop="address"
      label="Address">
    </el-table-column>
  </el-table>
</template>

<style>
  .el-table .info-row {
    background: #c9e5f5;
  }

  .el-table .positive-row {
    background: #e2f0e4;
  }
</style>

<script>
  export default {
    methods: {
      tableRowClassName(row, index) {
        if (index === 1) {
          return 'info-row';
        } else if (index === 3) {
          return 'positive-row';
        }
        return '';
      }
    },
    data() {
      return {
        tableData2:  [{
          date: '2016-05-03',
          name: 'Tom',
          address: 'No. 189, Grove St, Los Angeles'
        }, {
          date: '2016-05-02',
          name: 'Tom',
          address: 'No. 189, Grove St, Los Angeles'
        }, {
          date: '2016-05-04',
          name: 'Tom',
          address: 'No. 189, Grove St, Los Angeles'
        }, {
          date: '2016-05-01',
          name: 'Tom',
          address: 'No. 189, Grove St, Los Angeles'
        }]
      }
    }
  }
</script>
```
:::

### Table with fixed header

When there are too many rows, you can use a fixed header.

:::demo By setting the attribute `height` of `el-table`, you can fix the table header without any other codes.
```html
<template>
  <el-table
    :data="tableData3"
    height="250"
    border
    style="width: 100%">
    <el-table-column
      prop="date"
      label="Date"
      width="180">
    </el-table-column>
    <el-table-column
      prop="name"
      label="Name"
      width="180">
    </el-table-column>
    <el-table-column
      prop="address"
      label="Address">
    </el-table-column>
  </el-table>
</template>

<script>
  export default {
    data() {
      return {
        tableData3: [{
          date: '2016-05-03',
          name: 'Tom',

          name: 'Tom',
          address: 'No. 189, Grove St, Los Angeles'
        }, {
          date: '2016-05-04',
          name: 'Tom',
          address: 'No. 189, Grove St, Los Angeles'

          date: '2016-05-01',
          name: 'Tom',
          address: 'No. 189, Grove St, Los Angeles'

### Table with fixed column

When there are too many columns, you can fix some of them.

:::demo Attribute `fixed` is used in `el-table-column`, it accepts a `Boolean`. If `true`, the column will be fixed at left. It also accepts two string literals: 'left' and 'right', both indicating that the column will be fixed at corresponding direction.
```html
<template>
  <el-table

### Table with fixed columns and header

When you have huge chunks of data to put in a table, you can fix the header and columns at the same time.

:::demo  Fix columns and header at the same time by combining the above two examples.
```html
<template>
  <el-table
    :data="tableData3"
    border
    style="width: 100%"
    height="250">

### Fluid-height Table with fixed header (and columns)

When the the data is dynamically changed, you might want the table to have a maximum height rather than a fixed height and to show the scroll bar if needed.

:::demo  By setting the attribute `max-height` of `el-table`, you can fix the table header. The table body scrolls only if the height of the rows exceeds the max height value.
```html
<template>
  <el-table
    :data="tableData4"
    border
    style="width: 100%"

      label="Name"
      width="120">
    </el-table-column>

### Single select

Single row selection is supported.

:::demo Table supports single row selection. You can activate it by adding the `highlight-currnet-row` attribute. An event called `current-change` will be triggered when row selection changes, and its parameters are the rows after and before this change: `currentRow` and `oldCurrentRow`. If you need to display row index, you can add a new `el-table-column` with its `type` attribute assigned to `index`, and you will see the index starting from 1.
```html
<template>
  <el-table
    :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="Date"
      width="120">
    </el-table-column>
    <el-table-column
      property="name"
      label="Name"
      width="120">
    </el-table-column>
    <el-table-column
      property="address"
      label="Address">
    </el-table-column>
  </el-table>
</template>

<script>
  export default {
    data() {
      return {
        tableData: [{
          date: '2016-05-03',
          name: 'Tom',
          address: 'No. 189, Grove St, Los Angeles'
        }, {
          date: '2016-05-02',
          name: 'Tom',
          address: 'No. 189, Grove St, Los Angeles'
        }, {
          date: '2016-05-04',
          name: 'Tom',
          address: 'No. 189, Grove St, Los Angeles'
        }, {
          date: '2016-05-01',
          name: 'Tom',
          address: 'No. 189, Grove St, Los Angeles'
        }],
        currentRow: null
      }
    },

    methods: {
      handleCurrentChange(val) {
        this.currentRow = val;
      }
    }
  }
</script>
```
:::

### Multiple select

You can also select multiple rows.

:::demo Activating multiple selection is easy: simply add an `el-table-column` with its `type` set to `selection`. Apart from multiple selection, this example also uses `show-overflow-tooltip`: by default, if the content is too long, it will break into multiple lines. If you want to keep it in one line, use attribute `show-overflow-tooltip`, which accepts a `Boolean` value. When set `true`, the extra content will show in tooltip when hover on the cell.
```html
<template>
  <el-table
    :data="tableData3"
    border
    style="width: 100%"
    @selection-change="handleSelectionChange">
    <el-table-column
      type="selection"
      width="55">
    </el-table-column>
    <el-table-column
      label="Date"
      width="120">
      <template scope="scope">{{ scope.row.date }}</template>
    </el-table-column>
    <el-table-column
      property="name"
      label="Name"
      width="120">
    </el-table-column>
    <el-table-column
      property="address"
      label="Address"
      show-overflow-tooltip>
    </el-table-column>
  </el-table>
</template>

<script>
  export default {
    data() {
      return {
        tableData3: [{
          date: '2016-05-03',
          name: 'Tom',

          name: 'Tom',
          address: 'No. 189, Grove St, Los Angeles'
        }],
        multipleSelection: []
      }
    },

      handleSelectionChange(val) {
        this.multipleSelection = val;

### Sorting

Sort the data to find or compare data quickly.

:::demo Set table attribute `default-sort` to determine default sort column and order. Set attribute `sortable` in a certain column to sort the data based on this column. It accepts `Boolean` with a default value `false`. In this example we use another attribute named `formatter` to format the value of certain columns. It accepts a function which has two parameters: `row` and `column`. You can handle it according to your own needs.
```html
<template>
  <el-table
    :data="tableData"
    border
    :default-sort = "{prop: 'date', order: 'descending'}"
    style="width: 100%">
    <el-table-column
      prop="date"
      label="Date"
      sortable
      width="180">
    </el-table-column>
    <el-table-column
      prop="name"
      label="Name"
      width="180">
    </el-table-column>
    <el-table-column
      prop="address"
      label="Address"
      :formatter="formatter">

### Filter

Filter the table to find desired data.

:::demo Set attribute `filters` and `filter-method` in `el-table-column` makes this column filterable. `filters` is an array, and `filter-method` is a function deciding which rows are displayed. It has two parameters: `value` and `row`.
```html
<template>
  <el-table
    :data="tableData"
    border
    style="width: 100%">
    <el-table-column
      prop="date"
      label="Date"
      sortable
      width="180">
    </el-table-column>
    <el-table-column
      prop="name"
      label="Name"

          close-transition>{{scope.row.tag}}</el-tag>
      </template>
    </el-table-column>
  </el-table>
</template>

<script>
  export default {
    data() {
      return {
        tableData: [{
          date: '2016-05-03',
          name: 'Tom',
          address: 'No. 189, Grove St, Los Angeles',
          tag: 'Home'
        }, {
          date: '2016-05-02',
          name: 'Tom',

      }
    },
    methods: {
      formatter(row, column) {
        return row.address;

### Custom column template

Customize table column so it can be integrated with other components.
:::demo You have access to the following data: row, column, $index and store (state management of Table) by [Scoped slot](https://vuejs.org/v2/guide/components.html#Scoped-Slots). (Scoped slots is supported from `1.1`, `inline-template` still works, but it's not recommended).
```html
<template>
  <el-table
    :data="tableData"
    border
    style="width: 100%">
    <el-table-column
      label="Date"
      width="180">
      <template scope="scope">
        <el-icon name="time"></el-icon>
        <span style="margin-left: 10px">{{ scope.row.date }}</span>
      </template>
    </el-table-column>
    <el-table-column
      label="Name"
      width="180">
      <template scope="scope">
        <el-popover trigger="hover" placement="top">
          <p>Name: {{ scope.row.name }}</p>
          <p>Addr: {{ scope.row.address }}</p>
          <div slot="reference" class="name-wrapper">

      <template scope="scope">
        <el-button
          size="small"
          @click="handleEdit(scope.$index, scope.row)">Edit</el-button>
        <el-button
          size="small"
          type="danger"
          @click="handleDelete(scope.$index, scope.row)">Delete</el-button>
      </template>
    </el-table-column>
  </el-table>
</template>

<script>
  export default {
    data() {
      return {
        tableData: [{
          date: '2016-05-03',
          name: 'Tom',

### Expandable row

When the row content is too long and you do not want to display the horizontal scroll bar, you can use the expandable row feature.
:::demo Activate expandable row by adding type="expand" and scoped slot. The template for el-table-column will be rendered as the contents of the expanded row, and you can access the same attributes as when you are using `Scoped slot` in custom column templates.
```html
<template>
  <el-table
    :data="tableData3"
    style="width: 100%">
    <el-table-column type="expand">
      <template scope="props">
        <p>State: {{ props.row.state }}</p>
        <p>City: {{ props.row.city }}</p>
        <p>Address: {{ props.row.address }}</p>
        <p>Zip: {{ props.row.zip }}</p>
      </template>
    </el-table-column>
    <el-table-column
      label="Date"
      prop="date">
    </el-table-column>
    <el-table-column
      label="Name"
      prop="name">
    </el-table-column>
  </el-table>
</template>
