Combine column labels in the table header as an additional header

[leeangling]

When we create a new table header that combine multiple columns, the bottom border line is connected together. Can we add a new feature to not connect the bottom border line? one possible solution is to add a new border type that is indent at the start and end of border line.

This is a similar feature as gt tab_spanner() function. By default, the bottom line between tab_spanner() is not connected. Here is a gt example.

Thanks!

There is no direct support for indent in RTF format for border line. But you can hack the feature if you really need it.

I would not put it into r2rtf package as it is not a formal border line type supported by RTF file, you may consider to write and maintain a helper function for your organization if needed.

Here is a quick example to illustrate the idea.

library(r2rtf)
head(iris)[, 1:4] %>% 
  rtf_colheader(colheader = c(" | title 1 | | | title 2 | "), 
                col_rel_width = c(1, 8, 1, 1, 8, 1), 
                border_left =  c("single", "", "", "single", "", ""), 
                border_bottom = c("", "single", "", "", "single", "")) %>% 
  rtf_body(col_rel_width = c(5, 5, 5, 5), border_first = "") %>% 
  rtf_encode() %>% 
  write_rtf("tmp.rtf")

Thank you for providing the example solution. This solution can solve most of my problem in combining column labels. The extra separation cell may takes too many spaces when the table is too busy. Do you have a solution to reduce the space?

I thought the example already show you by controlling col_rel_width
