How do I maintain the formatting of text in a cell in an Excel spreadsheet when importing into R markdown?

Question

I have an .xlsx file in which some of the cells have boldface numbers and some have italicized numbers. I am using read_xlsx to read the .xlsx file into R and then using kable to present it with this code:

knitr::kable(spreadsheet, format="latex", booktabs = T) %>% 
kable_styling(latex_options = c("striped"))

I cannot get the boldface and italics numbers from the .xlsx to stay boldface and italicized when they appear in the .pdf generated from the .Rmd file. How do I do this?

在回答您的问题时，您无法维护格式化，但您可以复制它。

运行read_xlsx()函数时，它会从单元格中提取数据，但不保留任何格式。因此，任何粗体字体都不会自动传输到R。

实现所需内容的最简单方法是在将数据加载到R后添加粗体文本。kableExtra非常适合执行此类操作。以下是一个示例，使用column_spec和row_spec函数更改单元格的格式：

```{r}
library(kableExtra)

knitr::kable(iris[1:5,], format = "latex", booktab = TRUE) %>%
  column_spec(1, bold = T) %>%
  row_spec(0, bold = T, color = "red")

```

您可以自定义许多属性（运行?row_spec以加载帮助程序）：

• 字体大小
• 对齐
• 文字角度
• 文字颜色
• 背景颜色

如果您需要更精细地调整特定单元格的单元格格式，您可以调查cell_spec函数。
