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.

````jsx
import { TimePicker } from 'parkball';
import moment from 'moment';

const format = 'HH:mm';

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