# Use kable in Shiny

Since the output is just HTML, it’s very easy to use `kable` and `kableExtra` in the Shiny environment. For example:

    library(shiny)

    ui <- fluidPage(

       # Application title
       titlePanel("mtcars"),

       sidebarLayout(
          sidebarPanel(
             sliderInput("mpg", "mpg Limit",
                         min = 11, max = 33, value = 20)
          ),

          mainPanel(
             tableOutput("mtcars_kable")
          )
       )
    )

    server <- function(input, output) {
      library(dplyr)
      library(kableExtra)
       output$mtcars_kable <- function() {
         req(input$mpg)
         mtcars %>%
           mutate(car = rownames(.)) %>%
           select(car, everything()) %>%
           filter(mpg <= input$mpg) %>%
           knitr::kable("html") %>%
           kable_styling("striped", full_width = F) %>%
           add_header_above(c(" ", "Group 1" = 5, "Group 2" = 6))
       }
    }

    # Run the application
    shinyApp(ui = ui, server = server)

You can copy/paste the code above or simply run:

    shiny::runGist("https://gist.github.com/haozhu233/9e675e1a8a1bb4744f9ebc9246a2366b")
