Adding a vertical and horizontal scroll bar to the DT table in R shiny

问题

Please check the data table "Case Analyses Details" on the right. I want to fit the data table within the box, such that it aligns from right and bottom border in the box, such that we add a horizontal and vertical scroll bar to the DT which can be used to span the rows that overshoot the box.

## app.R ##
library(shiny)
library(shinydashboard)
library(DT)
ui <- dashboardPage(
dashboardHeader(title = "My Chart"),
dashboardSidebar(
width = 0
),
dashboardBody(
box(title = "Data Path", status = "primary",height = "595" ,solidHeader = T,
    plotOutput("trace_plot")),
box( title = "Case Analyses Details", status = "primary", height = 
"595",width = "6",solidHeader = T, 
     div(DT::dataTableOutput("trace_table",width = 220)))
))
server <- function(input, output) 
{ 
#Plot for Trace Explorer
output$trace_plot <- renderPlot({
plot(iris$Sepal.Length,iris$Sepal.Width)
})
output$trace_table <- renderDataTable({
mtcars
})
}
shinyApp(ui, server)

Something like this do?

rm(list = ls())
## app.R ##
library(shiny)
library(shinydashboard)
library(DT)
ui <- dashboardPage(
  dashboardHeader(title = "My Chart"),
  dashboardSidebar(
    width = 0
  ),
  dashboardBody(
    box(title = "Data Path", status = "primary",height = "595" ,solidHeader = T,
        plotOutput("trace_plot")),
    box( title = "Case Analyses Details", status = "primary", height = 
           "595",width = "6",solidHeader = T, 
         column(width = 12,
                DT::dataTableOutput("trace_table"),style = "height:500px; overflow-y: scroll;overflow-x: scroll;"
         )
    )))
server <- function(input, output) { 
  #Plot for Trace Explorer
  output$trace_plot <- renderPlot({
    plot(iris$Sepal.Length,iris$Sepal.Width)
  })
  output$trace_table <- renderDataTable({

    datatable(cbind(mtcars,mtcars), options = list(paging = FALSE))

  })
}
shinyApp(ui, server)
