Table | en-US |
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 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
:::
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.
:::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.
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.
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.
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.
:::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
:::
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. 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 property sets the algorithm used to lay out table cells, rows, and columns.
:::demo
table/table-layout

FAQ
How to use image preview in the table?
<el-table-column label="Thumbnail" width="180">
<template #default="scope">
<div style="display: flex; align-items: center">
<el-image :preview-src-list="srcList"/>
</div>
</template>
</el-table-column>
PS: since the fixed column is implement by sticky, when you have fixed columns in table, please add the preview-teleported
attribute in image
Why column is not rendered when use DOM templates?
Typical issue: #5046 #5862 #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
