为 Rmarkdown pdf 自定义 table

Question

我有一个 table 如下（dput 在最后）

# A tibble: 35 x 5
# Groups:   year [1]
   school_id class_id  year variable                value
       <dbl> <chr>    <dbl> <chr>                   <dbl>
 1       123 1         2020 sex_numerator_male        137
 2       123 1         2020 sex_numerator_female       67
 3       123 1         2020 sex_denominator_male   156986
 4       123 1         2020 sex_denominator_female 173055
 5       123 1         2020 age_numerator_18_34        76
 6       123 1         2020 age_numerator_35_54        97
 7       123 1         2020 age_numerator_55           31
 8       123 1         2020 age_denominator_18_34   98662
 9       123 1         2020 age_denominator_35_54  101261
10       123 1         2020 age_denominator_55     130118

我想做的是自定义 table 如下所示。我无法在 R 中解决它，因此粘贴了一个屏幕截图。应显示变量名称的相应值。为了便于理解，只显示table图中的变量名。

我正在使用 GT 包将数据组织成所需的 table。无法成功。除了性别、年龄，我还有其他行值。我正在尝试的是

控制 variable 列及其相应 values 的放置位置，格式类似于上面的示例 table 快照。
我将 table 按 3 列分组，School_id, class_id and year。因此，我可以分别为每个组生成 table。

如果有任何解决方案建议，我们将不胜感激。

Answer 1

这是您可以构建的示例：

library(dplyr)
library(kableExtra)

collapse_rows_dt <- data.frame(
  C1 = c(rep("Sex", 2), rep("Age", 5)),
  C2 = c("m", "f", "18-34", "35-44", "45-54", "55-64", "65+"),
  C3 = 1:7,
  C4 = sample(0:100, 7, replace = TRUE))

names(collapse_rows_dt) <- c("", "", "Total Number", "County")

kbl(collapse_rows_dt, align = "c") %>%
  # set background on first two columns
  column_spec(1:2, bold = T, background = "#999", width = "4em") %>% 
  # set background and font color on header row
  row_spec(0, bold = T, color = "#000", background = "#999") %>% 
  # add your header
  add_header_above(c("Class 1: Results for 2020" = 4)) %>% 
  # collapse the rows so they look "stacked"
  collapse_rows(columns = 1:2, valign = "top") %>% 
  # set a theme
  kable_classic(full_width = T)

这应该足以让您入门。一个问题是 kableExtra 不支持 HTML 中的垂直边框，仅支持 LaTeX。但是如果你能避免使用 LaTeX，你会更高兴。 kableExtra 调用的每一行都用注释分隔，该注释标识下一行的作用。 kableExtra 中有更多选项。

这是一个小插图，应该有你需要的一切：
