Shiny-RenderDataTable-Show Whitespace

Question

如何在闪亮的应用程序的呈现的数据表中显示空白？

[在下面运行该应用程序时-用户可以双击以编辑单元格，并在数据框'值'中看到前导空格。

不过，我不知道如何使空白可见！

library(shiny)
library(DT)
    ui = fluidPage(dataTableOutput("mytable"))
    server = function(input, output){
      values = data.frame(Demographics = c("Total", "Split_A", "Split_B", "Split_B1", "Split_B2"),check.names = F)

      output$mytable <- renderDT(
        values,
        selection = 'none',
        rownames = FALSE,
        escape   = FALSE,
        editable = T
      )
    }
  shinyApp(ui, server)
