#### 按钮组合
可以将多个 `Button` 放入 `Button.Group` 的容器中。
通过设置 `size` 为 `large` `small` 分别把按钮组合设为大、小尺寸。若不设置 `size`，则尺寸为中。

#### Button Group
Buttons can be grouped by placing multiple `Button` components into a `Button.Group`.
The `size` can be set to `large`, `small` or left unset resulting in a default size.
