# 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.
table/basic
:::
## Striped Table
Striped table makes it easier to distinguish different rows.
:::demo Attribute `stripe` accepts a `Boolean`. If `true`, table will be striped.
table/striped
:::
## Table with border
:::demo By default, Table has no vertical border. If you need it, you can set attribute `border` to `true`.
table/with-border
:::
## 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.
table/with-status
:::
## Table with show overflow tooltip
When the content is too long, it will break into multiple lines, you can use `show-overflow-tooltip` to keep it in one line.
:::demo Attribute `show-overflow-tooltip`, which accepts a `Boolean` value. When set `true`, the extra content will show in tooltip when hover on the cell.
table/show-overflow-tooltip
:::
## 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.
table/fixed-header
:::
## 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.
table/fixed-column
:::
## 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.
table/fixed-column-and-header
:::
## 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.
table/fixed-header-with-fluid-header
:::
## Grouping table head
When the data structure is complex, you can use group header to show the data hierarchy.
:::demo Only need to place el-table-column inside a el-table-column, you can achieve group header.
table/grouping-header
:::
## Table with fixed group header
fixed group head is supported
:::demo The attribute `fixed` of the group header is determined by the outermost `el-table-column`
table/fixed-column-and-group-header
:::
## Single select
Single row selection is supported.
:::demo Table supports single row selection. You can activate it by adding the `highlight-current-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.
table/single-select
:::
## Multiple select
You can also select multiple rows.
After ^(2.8.3), `toggleRowSelection` supports the third parameter `ignoreSelectable` to determine whether to ignore the selectable attribute.
:::demo Activating multiple selection is easy: simply add an `el-table-column` with its `type` set to `selection`.
table/multi-select
:::
## Sorting
Sort the data to find or compare data quickly.
:::demo Set attribute `sortable` in a certain column to sort the data based on this column. It accepts `Boolean` with a default value `false`. Set table attribute `default-sort` to determine default sort column and order. To apply your own sorting rules, use `sort-method` or `sort-by`. If you need remote sorting from backend, set `sortable` to `custom`, and listen to the `sort-change` event on Table. In the event handler, you have access to the sorting column and sorting order so that you can fetch sorted table data from API. 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.
table/sort
:::
## 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 three parameters: `value`, `row` and `column`.
table/filter
:::
## 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 [slot](https://v3.vuejs.org/guide/component-slots.html).
table/custom-column
:::
## Table with custom header
Customize table header so it can be even more customized.
:::demo You can customize how the header looks by header [slots](https://v3.vuejs.org/guide/component-slots.html).
table/custom-header
:::
## 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.
After ^(2.9.7), `preserve-expanded-content` is added to control whether to preserve expanded row content in DOM when collapsed.
:::demo Activate expandable row by adding type="expand" and 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 `slot` in custom column templates.
table/expandable-row
:::
## Tree data and lazy mode
:::demo You can display tree structure data. When row contains the `children` field, it is treated as nested data. For rendering nested data, the prop `row-key` is required. Also, child row data can be loaded asynchronously. Set `lazy` property of Table to true and the function `load`. Specify `hasChildren` attribute in row to determine which row contains children. Both `children` and `hasChildren` can be configured via `tree-props`.
table/tree-and-lazy
:::
## Selectable tree ^(2.8.0)
:::demo When `treeProps.checkStrictly` is true, the selection state of parent and child nodes is no longer associated, that is, when the parent node is selected, its child nodes will not be selected; when `treeProps.checkStrictly` is false, the selection state of parent and child nodes will be associated with the selection state of child nodes, that is, when the parent node is selected, all its child nodes will be selected.
table/check-strictly
:::
## Summary row
For table of numbers, you can add an extra row at the table footer displaying each column's sum.
:::demo You can add the summary row by setting `show-summary` to `true`. By default, for the summary row, the first column does not sum anything up but always displays 'Sum' (you can configure the displayed text using `sum-text`), while other columns sum every number in that column up and display them. You can of course define your own sum behaviour. To do so, pass a method to `summary-method`, which returns an array, and each element of the returned array will be displayed in the columns of the summary row, It can be a VNode or string. The second table of this example is a detailed demo.
table/summary
:::
## Rowspan and colspan
Configuring rowspan and colspan allows you to merge cells
:::demo Use the `span-method` attribute to configure rowspan and colspan. It accepts a method, and passes an object to that method including current row `row`, current column `column`, current row index `rowIndex` and current column index `columnIndex`. The method should return an array of two numbers, the first number being `rowspan` and second `colspan`. It can also return an object with `rowspan` and `colspan` props.
table/rowspan-and-colspan
:::
## Custom index
You can customize row index in `type=index` columns.
:::demo To customize row indices, use `index` attribute on `el-table-column` with `type=index`. If it is assigned to a number, all indices will have an offset of that number. It also accepts a method with each index (starting from `0`) as parameter, and the returned value will be displayed as index.
table/custom-index
:::
## Table Layout
The [table-layout](https://developer.mozilla.org/en-US/docs/Web/CSS/table-layout) property sets the algorithm used to lay out table cells, rows, and columns.
:::demo
table/table-layout
:::
## Tooltip formatter ^(2.9.4)
You can use `tooltip-formatter` to customize the tooltip content.
:::demo
table/tooltip-formatter
:::

## FAQ
#### How to use image preview in the table?
```vue{4}
<template>
<el-table-column width="180">
<template #default="scope">
<el-image preview-teleported :preview-src-list="srcList" />
</template>
</el-table-column>
</template>
```
#### Why column is not rendered when use DOM templates?
Typical issue: [#5046](https://github.com/element-plus/element-plus/issues/5046) [#5862](https://github.com/element-plus/element-plus/issues/5862) [#6919](https://github.com/element-plus/element-plus/issues/6919)
This is because the HTML spec only allows a few specific elements to omit closing tags, the most common being `<input>` and `<img>`. For all other elements, if you omit the closing tag, the native HTML parser will think you never terminated the opening tag
For more details please refer to [vue docs](https://vuejs.org/guide/essentials/component-basics.html#self-closing-tags)
