Add extra header second page and after in Tables that span multiple pages in PDF document

Open ujtwr opened this issue 2 years ago • 3 comments

When outputting PDF, flextable uses latex's "longtable". longtable allows for separate headers for the first page and the second and subsequent pages. I want to add text like "(continued)" at the top of the header for the second and subsequent pages. For this purpose,

I created the following function. Simply add text to the bottom of the latex source "\endfirsthead". It would be nice to be able to set any text, adjust font family, size, text alignment, etc. It might be nice if the footer could also be displayed on a page-by-page basis.

MyFunc <- function(x){
  tableNcol <- ncol_keys(x)
  
  if(!is.null(knitr::opts_knit$get("rmarkdown.pandoc.to"))){
    if(knitr::opts_knit$get("rmarkdown.pandoc.to") %in% c("beamer", "latex")) {
      flextable_to_rmd(x, print = FALSE) %>% 
        str_replace_all(
          fixed("\\endfirsthead"),
          fixed(str_glue("\\endfirsthead\n\n\\multicolumn{tableNcol}{{r}}{{(continued)}}\\\\", tableNcol=tableNcol))
        ) %>% 
        cat()
    }
  }else{
    return(x)
  }
}

If you use the following in a chunk, it will be rendered as is inline, and when knit, the latex source will be rewritten.

airquality %>% 
  slice(1:60) %>% 
  flextable() %>% 
  theme_booktabs() %>% 
  autofit() %>% 
  MyFunc()

Sorry for the delay

We will try, but no promise :)

In general, we are trying to add the same features for Word/PPTX/HTML/PDF but there it is a request for an exception for PDF only.

I would also love to see this feature in the Word files generated with flextable. A header on the following page ("Table 1 continued"), footer on the first page ("Table 1 continues on following page") or similar would be really helpful for some of the reports I've been using flextable for. I will continue searching to see if this type of thing is already out there for the docx people.

Unfortunately this feature does not exist in MS Word.
