显示内联

Question

我正在尝试使用R shiny创建一个应用程序，我在同一个框中使用fileinput和action按钮。我正面临着上面两个内联的问题。请参阅以下工作示例：

library(shiny)
library(shinydashboard)

ui <- dashboardPage(
  dashboardHeader(title = "Inline Widgets Issue"),
  dashboardSidebar(
  ),
  dashboardBody(  
    box(title = "Working Example",width=40 ,status = "warning", solidHeader = TRUE, collapsible = FALSE,
        fluidRow(column(width=8,fileInput('file1', 'Browse File',width="100%",
                                           accept=c('text/csv', 'text/comma-separated-values,text/plain', '.csv'))),
                        column(width=2,actionButton("save","Save!!")))
    ))
)

server <- function(input, output) {

}

shinyApp(ui, server)

目前情况如下： 我想要这样的东西：

您可以在操作按钮中添加样式标记：

library(shiny)
library(shinydashboard)

ui <- dashboardPage(
  dashboardHeader(title = "Inline Widgets Issue"),
  dashboardSidebar(
  ),
  dashboardBody(  
    box(title = "Working Example",width=40 ,status = "warning", solidHeader = TRUE, collapsible = FALSE,
        fluidRow(column(width=8,fileInput('file1', 'Browse File',width="100%",
                                          accept=c('text/csv', 'text/comma-separated-values,text/plain', '.csv'))),
                 column(width=2,actionButton("save","Save!!"))),
        tags$style(type='text/css', "#save { width:100%; margin-top: 25px;}")
    ))
)

server <- function(input, output) {

}

shinyApp(ui, server)

你也可以玩宽度和边距顶部来改变动作按钮的大小和位置。
