## 写在前面
此组件仅提供一个创建 `TreeTable` 的解决思路。它基于`element-ui`的 table 组件实现,通过`el-table`的`row-style`方法,在里面判断元素是否需要隐藏或者显示,从而实现`TreeTable`的展开与收起。
并且本组件充分利用 `vue` 插槽的特性来方便用户自定义。
`evel.js` 里面,`addAttrs` 方法会给数据添加几个属性,`treeTotable` 会对数组扁平化。这些操作都不会破坏源数据,只是会新增属性。
## Props 说明
| Attribute | Description | Type | Default |
| :--------------: | :--------------------------------- | :-----: | :------: |
| data | 原始展示数据 | Array | [] |
| columns | 列属性 | Array | [] |
| defaultExpandAll | 默认是否全部展开 | Boolean | false |
| defaultChildren | 指定子树为节点对象的某个属性值 | String | children | |
| indent | 相邻级节点间的水平缩进,单位为像素 | Number | 50 |
> 任何 `el-table` 的属性都支持,例如`border`、`fit`、`size`或者`@select`、`@cell-click`等方法。详情属性见`el-table`文档。
---
### 代码示例
```html
<tree-table :data="data" :columns="columns" border>
```
#### data(**必填**)
```js
const data = [
{
name:'1'
children: [
{
name: '1-1'
},
{
name: '1-2'
}
]
},
{
name: `2`
}
]
```
#### columns(**必填**)
- label: 显示在表头的文字
- key: 对应 data 的 key。treeTable 将显示相应的 value
- expand: `true` or `false`。若为 true则在该列显示展开收起图标
- checkbox: `true` or `false`。若为 true则在该列显示`checkbox`
- width: 每列的宽度,为一个数字(可选)。例如`200`
- align: 对齐方式 `left/center/right`
- header-align: 表头对齐方式 `left/center/right`
```javascript
const columns = [
{
label: 'Checkbox',
checkbox: true
},
{
label: '',
key: 'id',
expand: true
},
{
label: 'Event',
key: 'event',
width: 200,
align: 'left'
},
{
label: 'Scope',
key: 'scope'
}
]
```
> 树表组件将会根据 columns 的 key 属性生成具名插槽,如果你需要对列数据进行自定义,通过插槽即可实现
```html
<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
目前提供了几个方法,不过只是`beta`版本,之后很可能会修改。
```js
this.$refs.TreeTable.addChild(row, data) //添加子元素
this.$refs.TreeTable.addBrother(row, data) //添加兄弟元素
this.$refs.TreeTable.delete(row) //删除该元素
```
## 其他
如果有其他的需求,请参考[el-table](http://element-cn.eleme.io/#/en-US/component/table)的 api 自行修改 index.vue
# English
## 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 as `border`, `fit`, `size` or `@select`, `@cell-click`. See the ʻel-table` documentation for details.
---
### Example
```html
<tree-table :data="data" :columns="columns" border>
```
#### data(**Required**)
```js
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` or `false`
- checkbox: `true` or `false`
- width: column width 。such as `200`
- align: alignment `left/center/right`
- header-align: alignment of the table header `left/center/right`
```javascript
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.
```html
<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.
```js
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
```
## Other
If you have other requirements, please refer to the [el-table](http://element-cn.eleme.io/#/en-US/component/table) api to modify the index.vue

## 写在前面
此组件仅提供一个创建TreeTable的解决思路
## prop说明
#### *data*
**必填**
原始数据,要求是一个数组或者对象
```javascript
[{
key1: value1,
key2: value2,
children: [{
key1: value1
},
{
key1: value1
}]
},
{
key1: value1
}]
```
或者
```javascript
{
key1: value1,
key2: value2,
children: [{
key1: value1
},
{
key1: value1
}]
}
```
#### columns
列属性,要求是一个数组
1. text: 显示在表头的文字
2. value: 对应data的key。treeTable将显示相应的value
3. width: 每列的宽度,为一个数字(可选)
如果你想要每个字段都有自定义的样式或者嵌套其他组件columns可不提供直接像在el-table一样写即可如果没有自定义内容提供columns将更加的便捷方便
如果你有几个字段是需要自定义的几个不需要那么可以将不需要自定义的字段放入columns将需要自定义的内容放入到slot中详情见后文
```javascript
[{
value:string,
text:string,
width:number
},{
value:string,
text:string,
width:number
}]
```
#### expandAll
是否默认全部展开boolean值默认为false
#### evalFunc
解析函数function非必须
如果不提供,将使用默认的[evalFunc](./eval.js)
如果提供了evalFunc,那么会用提供的evalFunc去解析data并返回treeTable渲染所需要的值。如何编写一个evalFunc请参考[*eval.js*](https://github.com/PanJiaChen/vue-element-admin/blob/master/src/components/TreeTable/eval.js)或[*customEval.js*](https://github.com/PanJiaChen/vue-element-admin/blob/master/src/views/table/treeTable/customEval.js)
#### evalArgs
解析函数的参数,是一个数组
**请注意自定义的解析函数参数第一个为this.data第二个参数为 this.expandAll,你不需要在evalArgs填写。一定记住这两个参数是强制性的并且位置不可颠倒** *this.data为需要解析的数据this.expandAll为是否默认展开*
如你的解析函数需要的参数为`(this.data, this.expandAll,1,2,3,4)`,那么你只需要将`[1,2,3,4]`赋值给`evalArgs`就可以了
如果你的解析函数参数只有`(this.data, this.expandAll)`,那么就可以不用填写evalArgs了
具体可参考[*customEval.js*](https://github.com/PanJiaChen/vue-element-admin/blob/master/src/views/table/treeTable/customEval.js)的函数参数和[customTreeTable](https://github.com/PanJiaChen/vue-element-admin/blob/master/src/views/table/treeTable/customTreeTable.vue)的`evalArgs`属性值
## slot
这是一个自定义列的插槽。
默认情况下treeTable只有一行行展示数据的功能。但是一般情况下我们会要给行加上一个操作按钮或者根据当行数据展示不同的样式这时我们就需要自定义列了。请参考[customTreeTable](https://github.com/PanJiaChen/vue-element-admin/blob/master/src/views/table/treeTable/customTreeTable.vue)[实例效果](https://panjiachen.github.io/vue-element-admin/#/table/tree-table)
`slot`和`columns属性`可同时存在,columns里面的数据列会在slot自定义列的左边展示
## 其他
如果有其他的需求,请参考[el-table](http://element-cn.eleme.io/#/en-US/component/table)的api自行修改index.vue
