This reverts commit 84fab59c5a66828a6ccf1176796e508af47701da.

By watching TimelineChart Example:
[Charts Demo](https://pro.ant.design/components/Charts#scaffold-src-components-Charts-demo-mini-area)

```javascript
const chartData = [];
for (let i = 0; i < 20; i += 1) {
  chartData.push({
    x: (new Date().getTime()) + (1000 * 60 * 30 * i),
    y1: Math.floor(Math.random() * 100) + 1000,
    y2: Math.floor(Math.random() * 100) + 10,
  });
}
```

1. X-Axis (Timeline): The type should be like `number`.
2. Y-Axis (Value): The y2 may not be required if I just want to draw y1 only.

对`PageHeader`中的`tabList`展示逻辑做了更新，原本的实现会在外部传入一个空数组`tabList`时展现一个0出来（`tabList.length`的返回值）
