问题
I am creating a simple shiny app with some valuebox and three datatables.
If I design the app without using tabpanel everything works fine.
library(shiny)
library(shinydashboard)
library(DT)
ui <- dashboardPage(
dashboardHeader(title = "Dynamic boxes"),
dashboardSidebar(),
dashboardBody(
fluidRow(
valueBoxOutput("vbox1", width = 2),
valueBoxOutput("vbox2", width = 2),
valueBoxOutput("vbox3", width = 2),
valueBoxOutput("vbox4", width = 2),
valueBoxOutput("vbox5", width = 2),
valueBoxOutput("vbox6", width = 2)
),
fluidRow(
column(width = 4, box(title = "Iris", width = NULL, solidHeader = FALSE, dataTableOutput("dat1"))),
column(width = 4, box(title = "MT Cars", width = NULL, solidHeader = FALSE, dataTableOutput("dat2"))),
column(width = 4, box(title = "Old Faithful Gyser", width = NULL, solidHeader = FALSE, dataTableOutput("dat3")))
))
)
server <- function(input, output) {
output$vbox1 <- renderValueBox({ valueBox( "One","Yes",icon = icon("stethoscope"))})
output$vbox2 <- renderValueBox({ valueBox( "Two","Yes",icon = icon("stethoscope"))})
output$vbox3 <- renderValueBox({ valueBox( "Skip","Yes",icon = icon("stethoscope"))})
output$vbox4 <- renderValueBox({ valueBox( "a Two","Yes",icon = icon("stethoscope"))})
output$vbox5 <- renderValueBox({ valueBox( "Then","Yes",icon = icon("stethoscope"))})
output$vbox6 <- renderValueBox({ valueBox( "some","Yes",icon = icon("stethoscope"))})
output$dat1 <- renderDataTable({datatable(iris)})
output$dat2 <- renderDataTable({datatable(mtcars,extensions = 'Responsive' )})
output$dat3 <- renderDataTable({datatable(faithful,rownames = FALSE, options = list(autoWidth = TRUE) )})
}
shinyApp(ui, server)
Now if I design the app using tabpanel function there is a lot of wasted white space on the rightside.
library(shiny)
library(shinydashboard)
library(shinyBS)
library(DT)
ui <- dashboardPage(
dashboardHeader(),
dashboardSidebar(
sidebarPanel(
textInput("text", "Enter Id:"),
box(width = 1, background = 'purple'),
actionButton("Ok", "Press Ok",style='padding:8px; font-size:100%')
)
),
dashboardBody(
mainPanel(
tabsetPanel(
tabPanel("About", value=1, h6("The objective is to test width of ShinyApp in tabPanel design", br(),
br(),
"Distribution Prototype"
)
),
tabPanel("Data", value=2,
fluidRow(
valueBoxOutput("vbox1", width = 2),
valueBoxOutput("vbox2", width = 2),
valueBoxOutput("vbox3", width = 2),
valueBoxOutput("vbox4", width = 2),
valueBoxOutput("vbox5", width = 2),
valueBoxOutput("vbox6", width = 2)
),
fluidRow(
column(width = 4, box(title = "Iris", width = NULL, solidHeader = FALSE, dataTableOutput("dat1"))),
column(width = 4, box(title = "MT Cars", width = NULL, solidHeader = FALSE, dataTableOutput("dat2"))),
column(width = 4, box(title = "Old Faithful Gyser", width = NULL, solidHeader = FALSE, dataTableOutput("dat3"))))
)
)
)
))
server <- function(input, output) {
output$vbox1 <- renderValueBox({ valueBox( "One","Yes",icon = icon("stethoscope"))})
output$vbox2 <- renderValueBox({ valueBox( "Two","Yes",icon = icon("stethoscope"))})
output$vbox3 <- renderValueBox({ valueBox( "Skip","Yes",icon = icon("stethoscope"))})
output$vbox4 <- renderValueBox({ valueBox( "a Two","Yes",icon = icon("stethoscope"))})
output$vbox5 <- renderValueBox({ valueBox( "Then","Yes",icon = icon("stethoscope"))})
output$vbox6 <- renderValueBox({ valueBox( "some","Yes",icon = icon("stethoscope"))})
output$dat1 <- renderDataTable({datatable(iris)})
output$dat2 <- renderDataTable({datatable(mtcars,extensions = 'Responsive' )})
output$dat3 <- renderDataTable({datatable(faithful,rownames = FALSE, options = list(autoWidth = TRUE) )})
}
shinyApp(ui, server)
Wasted White Space Image
My usecase dictates that I use tabpanel, so any suggestions on making these objects span across the entire layout without wasting space is much appreciated.
