Table Spotlighting - 根据多列的值更改文本颜色

耶弗森

在我的情况下，我想用以下基础复制它，让我的颜色达到每行的最大值，这是我cell_spec()从kableExtra包中想到的问题

library(knitr)
library(kableExtra)


Name<-c("question1",  "question",  "question3",  "question4", 
        "question5",  "question6",  "question7",  "question8", 
        "question9",  "question10")
A<-c(0, 3 ,0 ,1, 0, 0, 0, 0, 2, 0)
B<-c(5, 0, 1, 0, 3, 0, 3, 1, 0, 1)
C<-c(3, 0, 2 ,2 ,0 ,1, 0 ,1 ,0 ,2)
D<-c(4, 1, 3 ,2 ,0 ,5, 0 ,1 ,3 ,2)

tab<-data.frame("Name"=Name,"A"=A,"B"=B,"C"=C,"D"=D)

tab%>%
  kbl() %>%
  kable_paper("striped",full_width = F)

请记住，我只想获得一个格式相似的表格，现在我将只显示表格中的最大数字

循环遍历数字列并根据值添加颜色（根据需要更改ifelse语句）：

tab %>%
  mutate_if(is.numeric, 
            function(i){
              cell_spec(i, color = ifelse(i > 1, "green", "red"))}) %>% 
  kbl(escape = FALSE) %>%
  kable_paper("striped", full_width = FALSE)

编辑：

每行做同样的事情，我们可以转置，然后如上所述循环列并根据值更改颜色，然后再次转置：

# transpose, get colour, transpose
tmp <- data.frame(t(
  data.frame(t(tab[ -1 ])) %>% 
  mutate_all(function(i) cell_spec(i, color = ifelse(i == max(i), "green", "red")))
  ), row.names = NULL)

# keep 1st name coloumn, add other formatted columns, and kable
cbind(tab[ 1 ], tmp) %>%
  kbl(escape = FALSE) %>%
  kable_paper("striped", full_width = FALSE)
