当我使用打开的xlsx软件包在R中导出excel文件时
如果我打开excel文件，则会显示以下消息：
"We found a problem with some content <nnnn>.xlsx. Do you want us to try and
recover as much as we can?"
我认为此问题来自Openxlsx软件包，
这是我的代码
openxlsx::write.xlsx( df, file = "NG.xlsx" , sheetName = "df" , col.names =
TRUE , row.names = FALSE )
我该如何解决R中的这个问题？
