r - Shiny 的应用程序中选项卡名称之间没有空格

Question

我已经创建了一个 Shiny 的应用程序，并且我渲染到 UI 的选项卡之间没有额外的间距。我正在使用 bs4dash Shiny 的 UI 框架。这个问题和这个框架有关吗？

code :

tabsetPanel(type = "tabs",
                          tabPanel(title = "abc", 

                                   rHandsontableOutput("contentsl"),tags$style(type="text/css", "#contentsl th {font-weight:bold;}")),
                          tabPanel(title = "fgh",
                                   rHandsontableOutput("content1"),tags$style(type="text/css", "#content1 th {font-weight:bold;}")),
                          tabPanel(title = "hjk",
                                   rHandsontableOutput("content2"),tags$style(type="text/css", "#content2 th {font-weight:bold;}")),
                          tabPanel(title="pqr",rHandsontableOutput("prem"),tags$style(type="text/css", "#prem th {font-weight:bold;}")),
                          tabPanel(title="Scatter Plot View",plotlyOutput("pl9",width = "100%",height = "600px")),
                          tabPanel(title = "Box Plot View",plotlyOutput("pl8",width = "100%",height = "600px")),
                          tabPanel(title = "Plot Data",rHandsontableOutput("pl.data",width = "100%",height = "100%"),tags$style(type="text/css","#pl.data th {font-weight:bold;}"))
                          ))

如果我在基本的 Shiny 应用程序(自动创建)中实现你的代码，它对我来说效果很好。这是代码(这并不是真正的答案，但它不适合评论，所以如果它没用，我将删除它):

library(plotly)

# Define UI for application that draws a histogram
ui <- fluidPage(

    # Application title
    titlePanel("Old Faithful Geyser Data"),

    # Sidebar with a slider input for number of bins 
    sidebarLayout(
        sidebarPanel(
            sliderInput("bins",
                        "Number of bins:",
                        min = 1,
                        max = 50,
                        value = 30)
        ),

        # Show a plot of the generated distribution
        mainPanel(
            tabsetPanel(
                type = "tabs",
                tabPanel(

            )
        )
        )
    )


# Define server logic required to draw a histogram
server <- function(input, output) {

    output$distPlot <- renderPlot({
        # generate bins based on input$bins from ui.R
        x    <- faithful[, 2]
        bins <- seq(min(x), max(x), length.out = input$bins + 1)

        # draw the histogram with the specified number of bins
        hist(x, breaks = bins, col = 'darkgray', border = 'white')
    })
