R语言垂直滚动不起作用。

Question

我想实现纵向滚动，但是这并没有起作用，有人能解释一下为什么吗？同时，我希望默认每次显示20行。

谢谢

output: 
  flexdashboard::flex_dashboard:
    orientation: columns
    vertical_layout: fill

```{r setup, include=FALSE}
library(flexdashboard)
library(DT)
```

Column {data-width=650}
-----------------------------------------------------------------------

### Chart A

```{r}
datatable(cars ,options = list(c(bPaginate = F, scrollY=T)),  filter = 'top')
```

“scrollY”参数不是布尔类型。根据datatables文档，您需要指定表的固定高度。请注意，不要解释内容并保留HTML标签。
