R垂直滾動不起作用

Question

我想獲得一個垂直滾動，但這是行不通的，任何人都可以解釋爲什麼？我也想默認一次顯示20行。

感謝

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

的scrollY參數不是一個布爾值。您需要指定表格的固定高度爲per the datatables documentation。
