## 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**
此组件仅提供一个创建 TreeTable 的解决思路,本组件充分利用 vue 插槽的特性,方便用户自定义
原始数据,要求是一个数组或者对象
```javascript
[{
key1: value1,
key2: value2,
children: [{
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。
调用 addAttrs 后,因\_\_parent 属性,会造成数据循环引用,使用 JSON.stringify()报错,所以转成 JSON 之前需要清除\_\_parent 属性。
## prop 说明
- data原始数据要求是一个数组或者对象
- columns列属性,要求是一个数组)
- renderContent数组扁平化方法可选
- defaultExpandAll默认是否全部展开默认全部展开
- defaultChildren子元素名默认为 children
- spreadOffset扩展符号的偏移量默认为 50px
- checkboxOffset复选框的偏移量默认为 50px
---
### 代码示例
- data(**必填**)
原始数据,
```js
const data = [
{
key1: value1,
key2: value2,
children: [
{
key1: value1
},
{
key1: value1
}]
},
{
key1: value1
}]
```
或者
```javascript
{
key1: value1,
key2: value2,
children: [{
key1: value1
},
{
key1: value1
}]
}
```
}
]
},
{
key1: value1
}
]
```
#### columns
列属性,要求是一个数组
或者
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)
```javascript
{
key1: value1,
key2: value2,
children: [{
key1: value1
},
{
key1: value1
}]
}
```
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
- columns
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
}]
```
1. label: 显示在表头的文字
2. key: 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)
#### expandAll
是否默认全部展开boolean值默认为false
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
#### evalFunc
解析函数function非必须
```javascript
const columns = [
// 建议第一列做展开收缩操作
{ label: '', key: '__spread', width: '200' },
// 如果添加复选框
{ label: '', key: '__checkbox', width: '200' },
{
label: string,
key: string,
width: number
},
{
label: string,
key: string,
width: number
}
]
```
如果不提供,将使用默认的[evalFunc](./eval.js)
#### renderContent
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)
解析函数function非必须
#### evalArgs
解析函数的参数,是一个数组
如果不提供,将使用默认的[evalFunc](./eval.js)
**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
## 其他
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
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
