Question

数据表无法在Shinydashboard中渲染。它只是为盒子呈现一条薄薄的白色条带。仅在RStudio中运行数据表函数会在RStudio查看器中呈现数据表。那么在闪亮的应用程序中呈现DT数据表的正确方法是什么？

## app.R ##
library(shiny)
library(shinydashboard)
library(htmlwidgets)
library(DT)
library(xtable)
source('../ts01/db.R')

ui <- dashboardPage(
  dashboardHeader(),
  dashboardSidebar(),
  dashboardBody(
    fluidRow(
      box(tableOutput("table1"))
    )
  )
)

server <- function(input, output) {
  output$table1 <- DT::renderDataTable({
    datatable(amount_data)
  })  
}

shinyApp(ui, server)

Answer 1

You should try the following:

1) tableOutput

rm(list = ls())
library(shiny)
library(shinydashboard)
my_data <- head(mtcars)

ui <- dashboardPage(
  dashboardHeader(),
  dashboardSidebar(),
  dashboardBody(
    fluidRow(
      box(tableOutput("table1"))
    )
  )
)

server <- function(input, output) {
  output$table1 <- renderTable({
    my_data
  })  
}

shinyApp(ui, server)

2) dataTableOutput

rm(list = ls())
library(shiny)
library(DT)
library(shinydashboard)

my_data <- head(mtcars)

ui <- dashboardPage(
  dashboardHeader(),
  dashboardSidebar(),
  dashboardBody(
    fluidRow(
      box(DT::dataTableOutput("table1"))
    )
  )
)

server <- function(input, output) {
  output$table1 <- DT::renderDataTable({
    datatable(my_data)
  })  
}

shinyApp(ui, server)

Answer 2

要确保使用正确的包来渲染数据表，请改用ui：

DT::dataTableOutput('table1')

数据表不会在闪亮仪表板中呈现
