R垂直滚动不起作用

Question

我想获得一个垂直滚动，但这是行不通的，任何人都可以解释为什么？我也想默认一次显示20行。

感谢

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

的scrollY参数不是一个布尔值。您需要指定表格的固定高度为per the datatables documentation。
