我在闪亮的中创建了以下面板
我首先在R 中导入以下库
library(shinydashboard)
library(shiny)
library(DT)
library(shinyWidgets)
library(readxl)
我们首先在这里创建UI，以提供日期、文件导入、nmeric输入和操作按钮
ui=shinyUI(
dashboardPage(
dashboardHeader(
title = "Chart",
titleWidth = 850
),
dashboardSidebar(
# Change font size here
tags$head(
tags$style(HTML(".main-sidebar { font-size: 20px; }"), style =
"background-color: #78d9c9;") #change the font size to 20
),
fileInput(inputId = "file", label = 'Load Dataset Here',placeholder =
"Upload",
multiple = TRUE,
accept = c("xlsx/xls",".xls",".xlsx"), width = "100%"),
dateInput(inputId = 'Cutoffdate',label = 'Cut Off date'),
numericInput(inputId = 'AAA',label = 'AAA', value = 0, min = 0, max =
120, step = 6),# Add new font color here
actionButton(inputId = 'Button',label ='Generate Chart', style="color:
#fff; background-color: #599AC3; border-color: #2e6da4, :font-color:
black")
),
dashboardBody(
tags$head(tags$style(HTML('
/* logo */
.skin-blue .main-header .logo {
background-color: #7CFC00;
}
/* logo when hovered */
.skin-blue .main-header .logo:hover {
background-color: #7CFC00;
}
/* navbar (rest of the header) */
.skin-blue .main-header .navbar {
background-color: #7CFC00;
}
# Sidebar color here
/* main sidebar */
.skin-blue .main-sidebar {
background-color: #F4A460;
}
/* active selected tab in the sidebarmenu */
.skin-blue .main-sidebar .sidebar .sidebar-menu
.active a{
background-color: #FFF8DC;
}
/* other links in the sidebarmenu */
.skin-blue .main-sidebar .sidebar .sidebar-menu
a{
background-color: #FFF8DC;
color:#A9A9A9;
}
/* other links in the sidebarmenu when hovered
*/
.skin-blue .main-sidebar .sidebar .sidebar-menu
a:hover{
background-color: #FFF8DC;
}
/* toggle button when hovered */
.skin-blue .main-header .navbar .sidebar-
toggle:hover{
background-color: #FFF8DC;
}
/* body */
.content-wrapper, .right-side {
background-color: #FFF8DC;
}
'))
),
mainPanel(
fluidRow(
column(12,plotlyOutput("plot1" , height = 600,
width=1200))
), fluidRow( column(7,tableOutput(outputId =
"Table2"))),
fluidRow(column(12,dataTableOutput(outputId =
"Table1")))
)
)
)
)
接下来我们创建一个服务器
server<-function(input, output){
output$Table1<-renderDataTable({airquality})
#output$plot1<-renderPlot({hist(airquality$Ozone)})
output$Table2<-renderTable({airquality})
}
shinyApp(ui, server =server)
主面板中的颜色背景并没有一直向下延伸。第二张桌子背景是白色的。有没有办法扩大输出面板的大小来进行
解决方案很简单。只需要删除UI中的mainpanel((。
