使用 openxlsx 按单元格填充颜色过滤 Excel 中突出显示的数据

我有一个很大的 Excel 表格（18k 行和 400 列），其中一些行使用不同的颜色突出显示。有没有办法使用按颜色过滤行openxlsx?

我首先加载了工作簿

wb <- loadWorkbook(file = "Items Comparison.xlsx")
getStyles(wb)
df <- read.xlsx(wb, sheet = 1)

我看到工作簿中使用的样式使用getStyles(wb)，但不确定如何使用该信息按颜色过滤每列的所有单元格。

 Cell border colours: #4E648A, #4E648A, #4E648A, #4E648A 
 Cell vert. align: top 
 Cell fill foreground:  rgb: #384C70 
 Cell fill background:  rgb: #384C70 
 wraptext: TRUE

我可以做什么来按填充颜色过滤数据？

UPDATE

基于@Henrik 解决方案，我尝试使用他的代码，但我不断收到错误。因此，为了了解发生了什么，我打印了输出x$style$fill$fillFg

我还是很困惑为什么只有 39 个项目。总行数是可变的，但不是 39。我也不理解该操作 - 是按行还是按列？

library(tidyxl)

formats <- xlsx_formats( "./temp/test_file.xlsx" )
cells <- xlsx_cells( "./temp/test_file.xlsx" )

#what colors are used?
formats$local$fill$patternFill$fgColor$rgb
# [1] NA         "FFC00000" "FF00B0F0" NA  

#find rows fo cells  with red background
cells[ cells$local_format_id %in%
         which( formats$local$fill$patternFill$fgColor$rgb == "FFC00000"), 
       "row" ]
