Prework

• Read and agree to the code of conduct and contributing guidelines.
• If there is already a relevant issue, whether open or closed, comment on the existing thread instead of posting a new issue.

Description

Describe the bug clearly and concisely.

Reproducible example

• Post a minimal reproducible example so the maintainer can troubleshoot the problems you identify. A reproducible example is:
  • Runnable: post enough R code and data so any onlooker can create the error on their own computer.
  • Minimal: reduce runtime wherever possible and remove complicated details that are irrelevant to the issue at hand.
  • Readable: format your code according to the tidyverse style guide.

tmp <- tibble(
  group = c("A", "A"),
  variable = c("B", "C"),
) |>
  gt(
    rowname_col = "Variable",
    row_group_as_column = TRUE
  ) |> 
  # remove full_name column

    label = "Group",
    rows = 1:2

Expected result

The rows should be merged using multirow from the multirow package (you would also need to load the package at the top).

\begin{longtable}{l|ll}
\toprule
\multicolumn{1}{l}{} & group & variable \\ 
\midrule\addlinespace[2.5pt]
\multirow{2}{*}{Group} & A & B \\ 
& A & C \\ 
\bottomrule
\end{longtable}

Session info

End the reproducible example with a call to sessionInfo() in the same session (e.g. reprex(session_info = TRUE)) and include the output.
