我刚刚将一个csv数据导入R的flexdashboard中,并希望将其显示在Chart网格之一中,下面是我正在使用的代码。我希望出现垂直和水平滚动条,但似乎这些滚动条不起作用,知道我错了吗?

对于数据,您可以使用MTCARS进行计时。

Row 
-------------------------------------

### DATA 

```{r}

    data_set <- reactive({
    inFile <- input$file1
    if (is.null(inFile))
      return(NULL) else return ( read.csv(inFile$datapath, header = input$header, stringsAsFactors =FALSE) )
}) 

output$tbl <-DT::renderDataTable({
  if (is.null(data_set()))
      return(NULL) else return (
        DT::datatable(data_set(), 
                      #style='bootstrap', class='table-condensed', 
                      #editable=FALSE, 
                      rownames=FALSE,
        options = list(
         scrollX = '400px', scrollY='360px', 
         searchHighlight=TRUE, pageLength = 4
  ))
)

})

div(style = "overflow-x: scroll; overflow-y: scroll;", DTOutput("tbl"))
```

添加数据:

structure(list(Gender = c("Male", "Male", "Male", "Male", "Male", 
"Male", "Male", "Male", "Male", "Male"), Height = c(73.847017017515,

2 个答案:

答案 0 :(得分:1)

尽管由于无法完全复制,所以无法在您的特定示例中对此进行测试,但是我可以共享在我当前的生产flexdashboard之一中工作的代码,该代码是在renderDT而不是{{ 1}},以避免命名冲突。在此示例中,renderDataTable是反应性的。

滚动由data_set()scrollX选项控制:

scrollY

答案 1 :(得分:1)

这是我的代码示例,renderDataTablescrollY 可以正常工作。我正在使用从本节更新的反应式 df。

renderDataTable({
  # Table only updates after the df as it is wrapped in an 
  # eventReactive
  if (!(is.null(query_data$$df))) {
    query_data$df %>% 
      select(JobID, PartID, `Short Desc`)
  }
},
options = list(
  scrollY = "43vh",
  dom = "ft",
  fixedColumns = TRUE,
  autoWidth = TRUE,
  ordering = TRUE,
  pageLength = -1)
)

关键部分是获得正确的选项,dom 选项允许您设置相当多的参数 dom = "ft" 启用过滤器并将其放置在表格上方。

pageLength = -1 显示 df 中的所有数据。
