My shiny application holds a table of 20-50 rows, and the users requested a fixed header.

After adding the fixed header we have scrolling issues though, if you scroll down +/- 5 lines it pops you back up to the top and this just keeps repeating.

I set my datatable up as follows:

    DT::datatable(data,
              caption = htmltools::tags$caption(style="caption-side: top; text-align: center; color:orange; font-size:200% ;",'Order Acceptance Requests'),
              rownames = FALSE,
              extensions = c("FixedHeader"),#, "Scroller"),
              options = list(paging = FALSE,
                             searching = FALSE,
                             columnDefs = ColSorting,
                             #deferRender = TRUE,
                             autoWidth = TRUE,
                             ordering = TRUE,
                             info = FALSE,
                             fixedHeader = TRUE,
                             #scroller = TRUE,
                             ScrollY = "200px",
                             pageLength = -1

              ))

I’ve tried playing around with Scroller but it doesn’t help me solve it (or I haven’t figured out how to solve it using Scroller).

I know that there used to be compatibility issues, but according to https://datatables.net/download/compatibility it should now work together.
