有没有办法在 gtsummary 中将两列折叠为一列?

Is there a way to collapse two columns to one in gtsummary?

我正在尝试折叠成列,以便拥有一个列以适应给定的 table 结构。所需的输出为 23 (21.2 - 24.5)。我已经创建了两个 table,但我似乎不明白。本质上,我希望比例和 CI 位于只有一个标题的单个列中 % (95% CI)

library(gtsummary)
library(tidyverse)

# Obtain proportions

tbl1 <-
  trial %>%
  mutate(trt = as.factor(trt)) %>%
  select(grade, response, trt) %>%
  tbl_summary(missing = "no",  type = everything() ~ "categorical",
              statistic = all_categorical() ~ "{p}")

myci2 <-
  tbl1$meta_data %>%
  filter(summary_type %in% c("categorical", "dichotomous")) %>%
  select(summary_type, var_label, df_stats) %>%
  unnest(df_stats) %>%
  mutate(
    conf.low = (p - qnorm(0.975) * sqrt(p * (1 - p) / N)) %>%
      style_percent(symbol = TRUE),
    conf.high =( p + qnorm(0.975) * sqrt(p * (1 - p) / N)) %>%
      style_percent(symbol = TRUE),
    ci = str_glue("{conf.low}, {conf.high}"),
    label = coalesce(variable_levels, var_label),
    row_type = ifelse(summary_type == "dichotomous", "label", "level")
  ) %>%
  select(variable, row_type, label, ci)


finaltbl <-
  tbl1 %>%
  modify_table_body(
    left_join,
    myci2,
    by = c("variable", "row_type", "label")
  ) %>%
  modify_header(ci = "**% (95% CI)**")

finaltbl

finaltbl[["table_body"]] <- finaltbl[["table_body"]] %>%
  mutate(prev = paste0(stat_0, " (", ci, ")")) 


finaltbl %>% 
  modify_column_unhide(prev) %>% 
  modify_column_hide(c(stat_0, ci))


示例如下!

myci2 <-
  tbl1$meta_data %>%
  filter(summary_type %in% c("categorical", "dichotomous")) %>%
  select(summary_type, var_label, df_stats) %>%
