R垂直滚动不起作用

Question

我正在尝试获得垂直卷轴，但这不起作用，任何人都可以解释原因吗？我还想默认一次显示20行。

谢谢

title: "Untitled"
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

scrollY参数不是布尔值。您需要将表格的固定高度指定为per the datatables documentation。
