Question

在启用ScrollX的情况下向右滚动时，我只是试图将最左边的列固定，而无法使其正常工作。知道我需要做些什么吗？

library(shiny)
library(DT)

ui <- fluidPage(
  fluidRow(mainPanel(DT::dataTableOutput('mtcars'), width = 12))
  )
server <- server <- function(input, output, session) {
  output$mtcars <- DT::renderDataTable({
    mtcars %>%
      DT::datatable(
        selection = 'none', rownames = '', filter = 'none',
        options = list(
          paging = TRUE, searching = TRUE, info = FALSE,
          sort = TRUE, scrollX = TRUE, fixedColumns = list(leftColumns = 1)
          )
        )
    })
  }
shinyApp(ui = ui, server = server)

两个问题：

您需要扩展名FixedColumns;
第一列实际上是leftColumns = 2，而不是leftColumns = 1（我想是行名）。

mtcars %>%
  DT::datatable(
    selection = 'none', rownames = '', filter = 'none',
    extensions = "FixedColumns",
    options = list(
      paging = TRUE, searching = TRUE, info = FALSE,
      sort = TRUE, scrollX = TRUE, fixedColumns = list(leftColumns = 2)
    )
  )

在向右滚动时无法修复Shiny DataTable中的列
