使用包openxlsx将多个样式（）应用于同一行

Question

我最近开始使用R包openxlsx，因为它根本不需要rJava包或Java。我正在尝试将日期写入列，但行格式未应用于xlsx文件中的最终日期列。

示例数据：

tmp <- structure(list(someNumbers = c(8L, 3L, 4L, 4L, 1L, 4L, 2L, 2L, 
       7L, 2L), someLetters = structure(c(9L, 4L, 1L, 2L, 7L, 3L, 4L, 
       6L, 8L, 5L), .Label = c("b", "d", "e", "h", "l", "n", "o", "t", 
       "u"), class = "factor"), moreNumbers = c(25L, 25L, 36L, 38L, 
       39L, 32L, 31L, 40L, 28L, 32L), moreStuff = c(0.37, 1.39, -2.27, 
       0.65, -0.71, -1.67, 0.71, 1.32, 2.14, 1.13), words = structure(c(5L, 
       3L, 7L, 1L, 2L, 6L, 4L, 10L, 9L, 8L), .Label = c("And another, but      
       maybe I'll make this one a little bit longer.", 
       "camera", "cat", "Ceramic penil holder made by yours truly.", 
       "dog", "headset", "Here's a list of words, almost like a    
       description.", 
       "Last", "Number 9.  Number 9.  Number 9.", "This phrase is not six     
       words long."
       ), class = "factor"), dates = structure(c(2000, 3217.55555555556, 
       4435.11111111111, 5652.66666666667, 6870.22222222222,     
       8087.77777777778, 
       9305.33333333333, 10522.8888888889, 11740.4444444444, 12958), class =    
       "Date")), .Names = c("someNumbers", 
       "someLetters", "moreNumbers", "moreStuff", "words", "dates"),    
       row.names = c(NA, 
       -10L), class = "data.frame")

和代码：

#Setting date options
options("openxlsx.dateFormat" = "yyyy-mm-dd")

#Create the xlsx workbook and insert a worksheet
testing <- createWorkbook()
addWorksheet(testing, "openxlsxTesting")

#Set column widths
setColWidths(testing, "openxlsxTesting", cols = 1:ncol(tmp), widths =    
"auto")

#Create a header style
headerStyle <- createStyle(fontColour = "white", fgFill =  
"blue", halign = "left", valign = "center", textDecoration =  
"bold")

#Create styles to shade alternate rows
lightStyle <- createStyle(fontColour = "black", fgFill = "#E7E0C5", halign = 
"right", valign = "center")

darkStyle <- createStyle(fontColour = "black", fgFill = "#E1D8B7", halign =  
"right", valign = "center")


#A vector of the xlsx rows
colorRows <- 2:(nrow(tmp)+1)

#Apply the header style
addStyle(testing, "openxlsxTesting", headerStyle, rows = 1, cols = 
1:ncol(tmp), gridExpand = TRUE)

#Apply the alternate shading styles
addStyle(testing, "openxlsxTesting", lightStyle, rows  = 
colorRows[which(colorRows %% 2 == 0)], cols = 1:ncol(tmp), gridExpand = TRUE)

addStyle(testing, "openxlsxTesting", darkStyle, rows =  
colorRows[which(colorRows %% 2 == 1)], cols = 1:ncol(tmp), gridExpand = TRUE)

#Write data to the workbook
writeData(testing, "openxlsxTesting", tmp, startRow = 1, startCol = 1)

#Save workbook to getwd()
saveWorkbook(testing, "openXlsxTesting.xlsx", TRUE)

我最终得到的是下面的图像几乎格式正确，但日期列没有阴影颜色。

我错过了什么吗？我已阅读文档但我无法找到将格式应用于日期字段的方法。我已经尝试专门格式化日期列，然后在应用日期格式后运行addStyle()，但它仍然是不行。

addStyle()函数如何将lightStyle或darkStyle应用于日期列？

任何帮助都将不胜感激。

Answer 1

样式被日期列样式覆盖。在添加任何样式之前调用writeData（）并在调用addStyle（）时设置stack = TRUE将解决此问题。我将在github上进行代码更改 https://github.com/awalker89/openxlsx以防止覆盖样式。
