dt - R垂直滚动不起作用

Question

我正在尝试垂直滚动，但这不起作用，有人可以解释为什么吗？我还想默认一次显示 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')
```

Answer 1

该scrollY参数不是布尔值。您需要根据datatables 文档指定表格的固定高度。
