+##prop说明
+###data 
+  必输
+  
+  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
+  必输
+  
+  列属性,要求是一个数组
+  
+  1. text: 显示在表头
+  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
+  ```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 
+  
+  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,请参考此目录下的*eval.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,你不需要在evalArgs填写。**
+  
+  如你的解析函数需要的参数为`(this.data,1,2,3,4)`,那么你只需要将`[1,2,3,4]`赋值给`evalArgs`就可以了
+ ## slot
+ 请参考`customTreeTable`
