R DT-编辑表格中的值

我不确定我是否理解正确,但这个解决方案可能会对你有所帮助。我把你的reactiveValues对象改成了reactiveValues对象,删除了replaceData行。

library(shiny)
library(DT)
shinyApp(
  ui = fluidPage(
    DTOutput('x1'),
    verbatimTextOutput("print")
  ),
  server = function(input, output, session) {
    x = reactiveValues(df = NULL)

    observe({
      df <- iris
      df$Date = Sys.time() + seq_len(nrow(df))
      x$df <- df
    })

    output$x1 = renderDT(x$df, selection = 'none', editable = TRUE)

    proxy = dataTableProxy('x1')

    observeEvent(input$x1_cell_edit, {
      info = input$x1_cell_edit
      str(info)
      i = info$row
      j = info$col
      v = info$value

      # problem starts here
      x$df[i, j] <- isolate(DT::coerceValue(v, x$df[i, j]))
    })

    output$print <- renderPrint({
      x$df
    })
  }
)

如果在DT中没有显示行名称,那么应该在 info$col 要获得正确的列,即:。, j = info$col + 1 .
