当任务状态正在发生，还在记录过程中，可用幽灵节点来表示当前的时间节点，当 pending 为真值时展示幽灵节点，如果 pending 是 React 元素可用于定制该节点内容，同时 pendingDot 将可以用于定制其轴点。reverse 属性用于控制节点排序，为 false 时按正序排列，为 true 时按倒序排列。

 en-US

When the timeline is incomplete and ongoing, put a ghost node at last. Set `pending` as truthy value to enable displaying pending item. You can customize the pending content by passing a React Element. Meanwhile, `pendingDot={a React Element}` is used to customize the dot of the pending item.
`reverse={true}` is used for reversing nodes.

import { Timeline, Button } from 'parkball';

class PendingTimeLine extends React.Component {
  state = {
    reverse: false,
  }

  handleClick = () => {
    this.setState({ reverse: !this.state.reverse });
  }

  render() {
    return (
      <div>
        <Timeline pending="Recording..." reverse={this.state.reverse}>
          <Timeline.Item>Create a services site 2015-09-01</Timeline.Item>
