我使用r中的一些包绘制了一个带有“datatable”的Map。为了在传单图中有更多的空间，我需要一个按钮来显示/隐藏datatable部分。怎么做？r代码如下：

library(leaflet)
library(DT)
library(crosstalk)

df <- read.csv(textConnection(
    "Name,Lat,Long
    Samurai Noodle,47.597131,-122.327298
    Kukai Ramen,47.6154,-122.327157
    Tsukushinbo,47.59987,-122.326726"
))

sdf <- SharedData$new(df, df$Name)

lflt<-leaflet(sdf) %>% addTiles() %>%
    addMarkers(~ Long, ~ Lat)%>%addEasyButtonBar(
easyButton(
 icon = htmltools::span(class = "star", htmltools::HTML("+")),
 onClick = JS("function(btn, map){ alert(\"Button 1\");}")))

bscols(lflt,      datatable(sdf, width = "100%"))
