react异常 Each child in a list should have a unique “key” prop

react异常警告：Each child in a list should have a unique “key” prop
原因：Dom在渲染数组时，需要一个key，不然嵌套数组时会引起歧义

解决：

{
  title:"customField",
  dataIndex:"customField",
  key:"customField",
  render:(text,record) => {
    return record.userCustomField.map(item,index) =>{
     return(
        <div key={index}>
           <Text delete={!record.enable}>{item.customFieldName}</Text>
        </div>
     )
  }
}
