+### Columns Type

+Using `columns-type` prop to control the type of columns.

+For example:
+
+- Pass in `['hour']` to select hour.
+- Pass in `['minute']` to select minute.
+- Pass in `['minute', 'second']` to select minute and second.
+- Pass in `['hour', 'minute', 'second']` to select hour, minute and second.

+### 选项类型
+
+通过 `columns-type` 属性可以控制选项的类型，支持以任意顺序对 `hour`、`minute` 和 `second` 进行排列组合。
+
+比如：
+
+- 传入 `['hour']` 来单独选择小时。
+- 传入 `['minute']` 来单独选择分钟。
+- 传入 `['minute', 'second']` 来选择分钟和秒。
+- 传入 `['hour', 'minute', 'second']` 来选择小时、分钟和秒。
