R 使用 formattable 更改数据框/HTML 表中文本的颜色

如何解决R 使用 formattable 更改数据框/HTML 表中文本的颜色

我想根据以下规则将不同颜色的文本添加到日期框或 HTML 表格中（能够定时破解变量）

即时 = 红色文本，秒 = 橙色文本，分钟 - 黄色文本，年 = 绿色文本。

我的数据框是

> dput(Final_DF)
structure(list(gender = c("female","male","female","male"),age = structure(c(47L,43L,65L,24L,44L,60L,26L,25L,62L,23L,61L,27L,47L,18L,34L,77L,71L,19L,64L,22L,55L,45L,29L,21L,20L,32L,68L,81L,63L,72L,38L,66L,39L,73L,53L,75L,69L,82L),class = c("variable","integer"
),varname = "Age"),web_browser = structure(c(1L,1L,4L,3L,2L,1L),.Label = c("Chrome","Internet Explorer","Firefox","netscape"),"factor"),varname = "browser"),Pswd = c("Password","abc1","football","Pr?hStMz3xuJ","Strawberries","JTA9sstLjU","Jazzed!","D!gU4","12345!","mQf0J?2","password1","CATS?","F!!FtBm","!!!!","HBpqA?xya9SIi","Os4Ft%D","fryj0t9KS","monkey","shadow","gpbvYZxYLBq7P","blackberries","Abc1!","p0$YpH4","SLOTH","Qwertyuiop","SqbmZZ!abHj","?Lnp6X6TNz","boatstatecat","shearer9","1B!aKnQm","DOGS","sunshine","pgJz8!Hdde","qwerty","1q2w3e4r5t","flightrockcups","ashley","Htkv5TDS51","C8cFMWH?a$S","cheesesteak","password!","aircraft","Se3PKKeg?dU","iloveyou","Bug!5$r","123","dragon","superman","password"),pswd_length = c(8L,8L,12L,10L,7L,5L,6L,9L,13L,11L,14L,8L),Time_to_crack = c("instant","instant","857 billion years","0.84 seconds","0.02 seconds","4.71 seconds","5.46 minutes","111 years","6.11 seconds","23 days","0.1 seconds","393 million years","3 months","49 years","81 trillion years","43.7 seconds","19.62 seconds","12 years","1.58 seconds","0.15 seconds","23 thousand years","2 million years","11 hours","5.81 seconds","1 year","4 thousand years","0.09 seconds","4 million years","0.34 seconds","23 hours","41 centuries","14 thousand years","11.26 seconds","0.3 seconds","8 thousand years","4 hours","instant")),row.names = c(NA,-50L),class = "data.frame")

我找到了这个formatable data frame walkthrough,but not sure how to apply it to my scenario

解决方法

这可以像这样实现：

1. 在小插图之后使用 ifelse 或使用例如定义格式化程序函数dplyr::case_when 定义了要应用的条件样式。
2. 在 formattable 中将此格式化程序应用于您的列 Time_to_crack

    library(formattable)
    library(dplyr)
    
    time_formatter <- formatter("span",style = x ~ style(color = dplyr::case_when(
                                  grepl("(instant|seconds)",x) ~ "red",grepl("(months|years)",x) ~ "green",grepl("hours",x) ~ "yellow",grepl("minutes",x) ~ "orange",TRUE ~ "black")))
    
    formattable(Final_DF,list(Time_to_crack = time_formatter))
