我让TableTools和ColVis一起工作,但是,正如另一篇文章(R shiny DataTables ColVis behavior)中所解释的那样,当单击“显示/隐藏列”按钮时,列表会混合下面表格中的值,并且我不能让名单消失。
在该帖子中提到闪亮的atm与当前的data.table版本不兼容,并且我想知道是否还有其他解决方案。这是我的代码:
ui.R
library(shiny)
library(shinythemes)
library(ggplot2)
addResourcePath('datatables','\\Users\\Ser\\Downloads\\DataTables-1.10.7\\DataTables-1.10.7\\media')
addResourcePath('tabletools','\\Users\\Ser\\Downloads\\TableTools-2.2.4\\TableTools-2.2.4')
shinyUI(fluidPage(theme = shinytheme("Journal"),
tags$head(
tags$style(HTML("
@import url('//fonts.googleapis.com/css?family=Lobster|Cabin:400,700');
"))
),
headerPanel(
h1("List Manager",
style = "font-family: 'Lobster', cursive;
font-weight: 500; line-height: 1.1;
color: #ad1d28;")),
sidebarLayout(
sidebarPanel(
#File Upload Manager
fileInput('file1', 'Choose file to upload'),
tagList(
singleton(tags$head(tags$script(src='//cdnjs.cloudflare.com/ajax/libs/datatables/1.10.7/js/jquery.dataTables.min.js',type='text/javascript'))),
singleton(tags$head(tags$script(src='//cdnjs.cloudflare.com/ajax/libs/datatables-tabletools/2.1.5/js/TableTools.min.js',type='text/javascript'))),
singleton(tags$head(tags$script(src='//cdnjs.cloudflare.com/ajax/libs/datatables-tabletools/2.1.5/js/ZeroClipboard.min.js',type='text/javascript'))),
singleton(tags$head(tags$link(href='//cdnjs.cloudflare.com/ajax/libs/datatables-tabletools/2.1.5/css/TableTools.min.css',rel='stylesheet',type='text/css'))),
singleton(tags$head(tags$script(src='//cdn.datatables.net/colvis/1.1.0/js/dataTables.colVis.min.js',type='text/javascript'))),
singleton(tags$script(HTML("if (window.innerHeight < 400) alert('Screen too small');")))
)),
mainPanel(
dataTableOutput("mytable"))
)))
server.R
shinyServer(function(input, output) {
output$mytable = renderDataTable({
inFile <- input$file1
if (is.null(inFile))
return(NULL)
read.table(inFile$datapath, header=TRUE, sep='')
}, options = list(
"dom" = 'TC<"clear">lfrtip',
"colVis" = list(
"activate"="click",
"align"="right"),
"oTableTools" = list(
"sSwfPath" = "//cdnjs.cloudflare.com/ajax/libs/datatables-tabletools/2.1.5/swf/copy_csv_xls.swf",
"aButtons" = list(
"copy",
"print",
list("sExtends" = "collection",
"sButtonText" = "Save",
"aButtons" = c("csv","xls")
)
)
)
)
)
})
我还有另一个问题:我想搜索&#34;&lt;&#34;或&#34;&gt;&#34;表底部搜索框中的值,但我无法使其工作。我不知道是否必须在代码中添加任何内容以便可以完成(例如&#34; regex&#34;或类似代码)。
答案 0 :(得分:0)
您可以尝试 DT 包,而不是自己攻击JS库。这是一个最小的例子:
library(shiny)
library(DT)
library(shinythemes)
shinyApp(
ui = fluidPage(
theme = shinytheme('journal'),
fluidRow(column(12, DT::dataTableOutput('foo')))
),
server = function(input, output) {
output$foo = DT::renderDataTable(
iris,
filter = 'bottom',
extensions = list(ColVis = list(activate= "click", align = "right")),
options = list(dom = 'C<"clear">lfrtip')
)
}
)
