#### columns
|
||||
列属性,要求是一个数组
|
||||
- columns
|
||||
|
||||
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)
|
||||
列属性,要求是一个数组
|
||||
|
||||
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
|
||||
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)
|
||||
|
||||
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
|
||||
}]
|
||||
```
|
||||
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
|
||||
|
||||
#### expandAll
|
||||
是否默认全部展开，boolean值，默认为false
|
||||
```javascript
|
||||
const columns = [
|
||||
// 建议第一列做展开收缩操作
|
||||
{ label: '', key: '__spread', width: '200' },
|
||||
{
|
||||
value: string,
|
||||
text: string,
|
||||
width: number
|
||||
},
|
||||
{
|
||||
value: string,
|
||||
text: string,
|
||||
width: number
|
||||
}
|
||||
]
|
||||
```
|
||||
|
||||
#### evalFunc
|
||||
解析函数，function，非必须
|
||||
|
||||
如果不提供，将使用默认的[evalFunc](./eval.js)
|
||||
解析函数，function，非必须
|
||||
|
||||
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)
|
||||
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。
|
||||
|
||||
#### 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*
|
||||
解析函数的参数，是一个对象，如果需要展开所有的数据，那么就传入`{expand:true}`
|
||||
|
||||
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
