MWE

Question

是否可以使用flexitable以一行脚本格式化多列？

该示例包含两种不同类型的double的变量。我想：

将大于1000的变量舍入到最接近的1000并添加千位逗号格式，
小于一到两位小数的圆形变量

使用flextable这是相对简单的，但是变成了具有更大数据集的孔。我找不到更有效率的方法。

我可以使用dplyr预处理数据（尽管逗号格式化需要将变量类型从double更改为character）。我希望尽可能在flextable中做到这一点。我知道Huxtable可以实现多列格式化。用户是否可以创建定制的set_formatter_type函数？

MWE

set.seed(100)

tib <- tibble(a = letters[1:4],
              b = runif(4)*sample(c(10000, 1000000, 10000000), 4, replace = TRUE),
              c = runif(4)*sample(c(10000, 1000000, 10000000), 4, replace = TRUE),
              d = runif(4)*sample(c(10000, 1000000, 10000000), 4, replace = TRUE),
              e = runif(4),
              f = runif(4))


  regulartable(tib) %>%
  set_formatter(b = function(x) format(round(x, -3), big.mark = ",")) %>% 
  set_formatter(c = function(x) format(round(x, -3), big.mark = ",")) %>% 
  set_formatter(d = function(x) format(round(x, -3), big.mark = ",")) %>% 
  set_formatter(e = function(x) round(x, 2)) %>%
  set_formatter(f = function(x) round(x, 2)) %>%
  print(preview = "docx")

是的，可以在此处找到文档：https://davidgohel.github.io/flextable/articles/format.html#set_formatter-function

在这里： https://davidgohel.github.io/flextable/reference/set_formatter.html

set_formatter(b = function(x) format(round(x, -3), big.mark = ","), 
              c = function(x) format(round(x, -3), big.mark = ","), 
              d = function(x) format(round(x, -3), big.mark = ","), 
              e = function(x) round(x, 2), 
              f = function(x) round(x, 2))

使用flextable r包格式化多个列
