闪亮的流体行列空白 [英] shiny fluidrow column white space

问题描述

我有一个顶部横幅，我想将其分成代表两个不同输入的两个独立部分.为此，我创建了一个 fluidRow 并有两列，每个输入一列.但是，尽管设置了 offset = 0，但现在列之间还是有一点空白.有什么办法可以删除这个空白，使列紧挨着?

I have a top banner that I want to split into two separate sections representing two different inputs. To do this, I've created a fluidRow and with two columns, one for each input. However, as it is now there is a little bit of white space between the columns, despite putting offset = 0. Is there any way to remove this white space so that the columns are immediately next to one another?

colors = c("green","blue","red")
library(shiny)

ui <- fluidPage(

  tabsetPanel(
    tabPanel("Info",
             fluidRow( 
                   column(width = 6, offset = 0,
                      div(style = "height:50px;width:100%;background-color: #999999;border-style: solid;border-color: #000000",
                          tags$h3("Section 1")
                      )
                   ),
                   column(width = 6, offset = 0,
                       div(style = "height:50px;width:100%;background-color: #999999;border-style: solid;border-color: #000000",       
                          tags$h3("Section 2")
                       )
                   ) 
             ),
             fluidRow(

                       selectInput(inputId = "color",label = "color:",
                                   choices = colors,
                                   selected = colors[2],
                                   multiple = FALSE)
                      )

                   column(width = 6, offset = 0,
                          div(style = "height:50px;width:100%;background-color: #999999;border-style: solid;border-color: #000000",       
                              selectInput(inputId = "points",label = "Number of Points:",

             fluidRow(
                   plotOutput("plot", width = "100%")
             )

    )
  )

  data = eventReactive(input$go, {
    var1 = rnorm(isolate(as.numeric(input$points)),5)

  output$plot = renderPlot({
    plotdata = data()
    plotcol = isolate(input$color)
    plot(plotdata$var1, col = plotcol)

推荐答案

空白是 div 列的填充.要删除它，请使用

The white space is the padding of the column div. To remove that, use

column(width = 6, offset = 0, style='padding:0px;', ...)
