tooltip or popover in Shiny datatables for each cell?

Question

Is there any way to get a tooltip for each and every cell in datatable in r shiny? There are so many ways to get the hover row or column. But I could not find a way to get both row and column index and show a different hover tooltip for each and every cell. Can anyone modify the following code?

library(shiny)
library(DT)

shinyApp(
  ui = fluidPage(
    dataTableOutput('table'),
    verbatimTextOutput('hoverIndex'),
  ),

  server = function(server, input, output) {

    output$hoverIndex <- renderText({
      UI_out <- input$hoverIndexJS
      return(paste("hover column info", UI_out))
    })


    output$table <- renderDataTable({
      DT_out <- data.frame(`A` = 1:5, `B` = 11:15, `C` = LETTERS[1:5])
      DT_out <- datatable(DT_out
                          ,rownames = F
                          ,callback = JS("
                                         /* code for columns on hover */
                                         table.on('mouseenter', 'td', function() {
                                         var td = $(this);
                                         var col = table.cell( this ).index().columnVisible;
                                         var row = table.cell( this ).index().row;
                                         $('td[row][col]).attr('title', row+col);
                                         Shiny.onInputChange('hoverIndexJS', info_out);

                                         });"

                          )
                          )
      return(DT_out)
  })
    }
      )
