|

## zh-CN
|
||
|
|
||
|
嵌套表单字段需要对 `field` 进行拓展,将 `field.name` 和 `field.fieldKey` 应用于控制字段。
|
||
|
|
||
|
## en-US
|
||
|
|
||
|
Nest dynamic field need extends `field`. Pass `field.name` and `field.fieldKey` to nest item.

const Demo = () => {
|
||
|
const onFinish = values => {
|
||
|
console.log('Received values of form:', values);
|
||
|
};

return (
|
