框()的shinydashboard列布局

Question

我有一个如下所示的shinydashboard：

​

​

# Packages
library(shinydashboard)
library(tidyverse)
library(readxl)
library(scales)
theme_set(theme_light())


header <- dashboardHeader(
  title = "Test App",
  titleWidth = 215
)

sidebar <- dashboardSidebar(
  sidebarMenu(
    menuItem("Test Tab", tabName = "test_tab",
             icon = icon("paper-plane"), startExpanded = TRUE)
  )
)


body <- dashboardBody(
  tabItems(
    tabItem(tabName = "test_tab",

            fluidRow(
              column(width = 4,
                     h2("Column X"),
                     valueBoxOutput("first_value", width = NULL),
                     box(flexdashboard::gaugeOutput("second_value", width = "90%", height = "100px"),
                         title = "Second Value", status = "primary", solidHeader = TRUE,
                         collapsible = FALSE, width = NULL
                     )
              ),
              column(width = 8,
                     h2("Column Y"),

                     box(
                       title = "#3", status = "primary", solidHeader = TRUE,
                       collapsible = FALSE, width = 4
                     ),
                     box(
                       title = "#4", status = "primary", solidHeader = TRUE,
                       collapsible = FALSE, width = 4
                     )
              )
            ),

            fluidRow(
              h2("Row A"),

              column(width = 12,

                     box(title = "Third Value", status = "primary", solidHeader = TRUE,
                         width = 2.4),

                     box("Fourth Value", status = "primary", solidHeader = TRUE,
                         width = 2.4),

                     box("Fifth Value", status = "primary", solidHeader = TRUE,
                         width = 2.4),


                     box("Sixth Value", status = "primary", solidHeader = TRUE,
                         width = 2.4),


                     box("Seventh Value", status = "primary", solidHeader = TRUE,
                         width = 2.4)
              )


            )

    )
  )
)


# Put them together into a dashboardPage
ui <- dashboardPage(skin = "blue", header = header,
                    sidebar = sidebar,
                    body = body)


server <- function(input, output) {

  output$first_value <- renderValueBox({

    valueBox(
      comma_format()(100000),
      subtitle = "First Value",
      icon = icon("list"), color = "purple"
    )
  })

  output$second_value = flexdashboard::renderGauge({
    flexdashboard::gauge(0.12 * 100,
                         symbol = '%',
                         min = 0, 
                         max = 100)
  })

}

shinyApp(ui, server)

我正在尝试让RowA下面的框()以五列的格式排列，如下所示：

Third Value | Fourth Value | Fifth Value | Sixth Value

我不确定在这里我该怎么做。我试着在fluidRow()中的column()中放置了5个框，但不幸的是，框总是水平显示……

有没有办法以列的形式显示这些框？如果没有，你能指导我使用与我的功能相似的其他功能吗？

Answer 1

您已经将这五个框中每个框的列宽指定为2.4 (我猜是12/5)。

列宽应为整数。如果你用2.4代替2，它就会工作得很好。

请注意，您将在框5的右侧有一个空列，对应于剩余的2 (12 - 2*5)个位置。

这是基于引导列布局的。有关详细信息，请参阅this教程。
