Issues with row_group_as_column = TRUE + row names

[olivroy]

Stub creation seems quite affected by row names and row groups. rowname_col, groupname_col and row_group.as_columns in general.

This is a list of issues that are related to this. Fixing the logic in dt_ creation may fix many issues automatically!

• Doesn't have effect with interactive tables (probably won't fix unless reactable changes something)
• Misalignment of cells using summary_rows(..., side = "top") and row groups as columns #1561
• Ability to add multiple stubhead labels when row_group.as_column = TRUE #1408
• row_group.as_column=TRUE does not work for Word outputs #1407
• cols_width() is off by one column when row_group.as_column = TRUE #1253
• Footnotes not printing marker when row_group.as_column is set to TRUE #1001
• fmt_markdown() doesnt affect group cols #1579
• tab_row_group with row_group_as_column = TRUE not merging rows #1557
• rows_add after styling may style incorrect row #1674
• Setting cols_width causes column to "disappear" #1510
• cols_hide does not work for rowname_col #1550
• tab_row_group with row_group_as_column = TRUE yields sprintf error (read comments) #1552
• rows_add() creates an incorrect stub #1471
• Automatically prefix row groups #1425
• Multiple rowname cols entry #1406

multiple row groups

From #1552 (comment)

This simple example doesn't render due the alignment not being properly set.

# the error is not useful as the error occurs before.
# instead of being stub_1 , var is c("trim", "mfr")

gt::gtcars |> dplyr::group_by(trim, mfr) |> gt::gt(row_group_as_column = T)
#> Error in sprintf("<%s %s%sclass=\"gt_row %s%s\"%s>%s</%s>", elements,  :
#>  Can't recycle elements
#> 
#> Dans boxhead$var == var :
#> Wrong size ( var has length 2)

@rich-iannone if you have any clue on where to fix this, it would be great. It feels like a well-placed change would possibly fix
