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.
<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'
}]
}
}
}

:::
Striped Table
Striped table makes it easier to distinguish different rows.
:::demo Attribute stripe accepts a Boolean. If true, table will be striped.

Table with border
:::demo By default, Table has no vertical border. If you need it, you can set attribute border to true.
<template>
<el-table

:::
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 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 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.

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.

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.

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.

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.

Filter
Filter the table to find desired data.

Custom column template
Customize table column so it can be integrated with other components.

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.

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.

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 rowsapn and colspan props.
