layUI treeTable.js:271 Uncaught TypeError: Cannot read property 'children' of undefined

最近用到layUI的treetable，官方給的數據沒有問題，

自己改的就GG，總是報 treeTable.js:271 Uncaught TypeError: Cannot read property 'children' of undefined

然後折騰半天，發現第一個參數必須叫做id

我的數據源爲 ：

data=[{'id': '4.0000000005591e-06',"cost":"545456" ,"children":[{'id': '4.9999999873762e-06',"cost":"4545asdasdd" } ]  } ]

數據源第一參數名必須爲id，不然就報錯，想顯示其他名稱可以在渲染表格時改title

 {field: "id1", title:"cost"}

我的就改成了cost
