TimePicker 浮层中的列会随着 format 变化，当略去 format 中的某部分时，浮层中对应的列也会消失。

en-US

While part of format is omitted, the corresponding column in panel will disappear, too.

import { TimePicker } from 'antd';
import moment from 'moment';

const format = 'HH:mm';

ReactDOM.render(
  <TimePicker defaultValue={moment('12:08', format)} format={format} />,
  mountNode
);
