Tree-Table
Brief
This component only provides a solution for creating TreeTable
. It is based on the element-ui
table component. It uses the row-style
method of el-table
to determine whether the element needs to be hidden or displayed.
And this component makes full use of the features of the vue
slot to make it user-friendly.
In evel.js
, the addAttrs
method adds several properties to the data, and treeTotable
flattens the array. None of these operations will destroy the source data, just add properties.
Props
Attribute | Description | Type | Default |
---|---|---|---|
data | original display data | Array | [] |
columns | column attribute | Array | [] |
defaultExpandAll | whether to expand all nodes by default | Boolean | false |
defaultChildren | specify which node object is used as the node's subtree | String | children |
indent | horizontal indentation of nodes in adjacent levels in pixels | Number | 50 |
Any of the
el-table
properties are supported, such asborder
,fit
,size
or@select
,@cell-click
. See the ʻel-table` documentation for details.
Example
<tree-table :data="data" :columns="columns" border>
data(Required)
const data = [
{
name:'1'
children: [
{
name: '1-1'
},
{
name: '1-2'
}
]
},
{
name: `2`
}
]
columns(Required)
- label: text displayed in the header
- key: data.key will show in column
- expand:
true
orfalse
- checkbox:
true
orfalse
- width: column width 。such as
200
- align: alignment
left/center/right
- header-align: alignment of the table header
left/center/right
const columns = [
{
label: 'Checkbox',
checkbox: true
},
{
label: '',
key: 'id',
expand: true
},
{
label: 'Event',
key: 'event',
width: 200,
align: 'left'
},
{
label: 'Scope',
key: 'scope'
}
]
The tree table component will generate a named slot based on the key property of columns. If you need to customize the column data, you can do it through the slot.
<template slot="your key" slot-scope="{scope}">
<el-tag>level: {{ scope.row._level }}</el-tag>
<el-tag>expand: {{ scope.row._expand }}</el-tag>
<el-tag>select: {{ scope.row._select }}</el-tag>
</template>
Events
Several methods are currently available, but only the beta
version, which is likely to be modified later.
this.$refs.TreeTable.addChild(row, data) //Add child elements
this.$refs.TreeTable.addBrother(row, data) //Add a sibling element
this.$refs.TreeTable.delete(row) //Delete the element
