【问题描述】：

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

instant = 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", "male", "female", 
"female", "male", "male", "male", "male", "female", "male", "male",

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

标签： r formattable

【解决方案1】：

这可以这样实现：

在小插图之后，使用 ifelse 或使用例如定义格式化函数dplyr::case_when 定义要应用的条件样式。
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))
