使用 tableOutput 更改单行数据框字体颜色的最简单方法是什么？具体来说，如何将“Right”下的“7”改为绿色。

library(shiny)

shinyApp(
  ui = fluidPage(

    sidebarLayout(
      sidebarPanel(
      fluidRow(  
         tableOutput("view")
        )
      ),

      mainPanel(
      ))),

  server = function(input, output, session){

    correct <- reactiveValues(num = 7)
    wrong <- reactiveValues(num = 4)   
    skipped <- reactiveValues(num = 9)

    togo = 80

    output$view <- renderTable(tibble(
      Right = correct$num,
      Wrong = wrong$num,
      Skipped = skipped$num,
      ToGo = togo
    ), spacing = "xs")
  }
)

在这种情况下最好使用DT 附带renderDataTable 以获得更好的格式。

library(shiny)
library(tidyverse)
library(DT)

shinyApp(
  ui = fluidPage(

    sidebarLayout(
      sidebarPanel(
        fluidRow(  
          column(8,dataTableOutput("view"))
        )
      ),

      mainPanel(
      ))),

  server = function(input, output, session){

    correct <- reactiveValues(num = 7)
    wrong <- reactiveValues(num = 4)   
    skipped <- reactiveValues(num = 9)

    togo = 80

    output$view <- renderDataTable(datatable(tibble(
      Right = correct$num,
      Wrong = wrong$num,
      Skipped = skipped$num,
      ToGo = togo
    )) %>% formatStyle("Right",color=styleEqual(7, "red")) ) 
  }
)

仅显示表格：

library(shiny)
library(tidyverse)
library(DT)

shinyApp(
  ui = fluidPage(

    sidebarLayout(
      sidebarPanel(
        fluidRow(  
          column(8,dataTableOutput("view"))
        )
      ),

      mainPanel(
      ))),

  server = function(input, output, session){

    correct <- reactiveValues(num = 7)
    wrong <- reactiveValues(num = 4)   
    skipped <- reactiveValues(num = 9)

    togo = 80

    output$view <- renderDataTable(datatable(tibble(
      Right = correct$num,
      Wrong = wrong$num,
      Skipped = skipped$num,
      ToGo = togo
    ), options = list(dom = 't')) %>% formatStyle("Right",color=styleEqual(7, "red")) ) 
  }
)

这个选项带来了很多我想隐藏的功能。是否可以隐藏：显示条目、搜索框、列名旁边的向上/向下小箭头、行名、“显示 1 到 1 个条目”和上一个/下一个？
太棒了。谢谢。不过仍然有那些矫枉过正的三角形。
