r - 如何使用 R 中的 `openxlsx` 包在单元格范围周围应用粗边框

Question

我在 R 中加载了一个 Excel 工作簿，并希望对矩形单元格范围中的边框进行一些格式化。

我想在所有单元格之间放置一个细边框

在单元格范围的外部放置一个粗边框。

目前，我只能看到以下方法(如下面的代码所示):

在

范围内添加细边框

用左粗边框和其​​他细边框覆盖左侧单元格

用右侧粗边框和其​​他细边框覆盖右侧单元格

用正确的边框分别覆盖每个角单元格

有没有更简单的方法来实现这一目标？

如果我使用 stack = TRUE在第二个电话中，我可以跳过角落:

library(openxlsx)

wb <- openxlsx::createWorkbook()
openxlsx::addWorksheet(
  wb = wb,
  sheetName = "Borders"
)

rangeRows = 2:5
rangeCols = 4:8

insideBorders <- openxlsx::createStyle(
  border = c("top", "bottom", "left", "right"),
  borderStyle = "thin"
)
openxlsx::addStyle(
  wb = wb,
  sheet = "Borders",
  style = insideBorders,
  rows = rangeRows,
  cols = rangeCols,
  gridExpand = TRUE
)

openxlsx::openXL(wb)

## left borders
openxlsx::addStyle(
  wb = wb,
  sheet = "Borders",
  style = openxlsx::createStyle(
    border = c("left"),
    borderStyle = c("thick")
  ),
  rows = rangeRows,
  cols = rangeCols[1],
  stack = TRUE,
  gridExpand = TRUE
)

##right borders
openxlsx::addStyle(
  wb = wb,
  sheet = "Borders",
  style = openxlsx::createStyle(
    border = c("right"),
    borderStyle = c("thick")
  ),
  rows = rangeRows,
  cols = tail(rangeCols, 1),
  stack = TRUE,
  gridExpand = TRUE
)

## top borders
openxlsx::addStyle(
  wb = wb,
  sheet = "Borders",
  style = openxlsx::createStyle(
    border = c("top"),
    borderStyle = c("thick")
  ),
  rows = rangeRows[1],
  cols = rangeCols,
  stack = TRUE,
  gridExpand = TRUE
)

##bottom borders
openxlsx::addStyle(
  wb = wb,
  sheet = "Borders",
  style = openxlsx::createStyle(
    border = c("bottom"),
    borderStyle = c("thick")
  ),
  rows = tail(rangeRows, 1),
  cols = rangeCols,
  stack = TRUE,
  gridExpand = TRUE
)

openxlsx::openXL(wb)

原始代码:

library(openxlsx)

wb <- openxlsx::createWorkbook()
openxlsx::addWorksheet(
  wb = wb,
  sheetName = "Borders"
)

rangeRows = 2:5
rangeCols = 4:8

insideBorders <- openxlsx::createStyle(
  border = c("top", "bottom", "left", "right"),
  borderStyle = "thin"
)
openxlsx::addStyle(
  wb = wb,
  sheet = "Borders",
  style = insideBorders,
  rows = rangeRows,
  cols = rangeCols,
  gridExpand = TRUE
)

openxlsx::openXL(wb)

leftBorders <- openxlsx::createStyle(
  border = c("top", "bottom", "left", "right"),
  borderStyle = c("thin", "thin", "thick", "thin")
)

openxlsx::addStyle(
  wb = wb,
  sheet = "Borders",
  style = leftBorders,
  rows = rangeRows,
  cols = rangeCols[1],
  gridExpand = TRUE
)

openxlsx::openXL(wb)

我知道这是一个较旧的问题，但如果有人遇到这个问题，这里有一个函数，它只将边框应用于您传递的行和列参数的外部:

OutsideBorders <-
  function(wb_,
           sheet_,
           rows_,
           cols_,
           border_col = "black",
           border_thickness = "medium") {
    left_col = min(cols_)
    right_col = max(cols_)
    top_row = min(rows_)
    bottom_row = max(rows_)
    
    sub_rows <- list(c(bottom_row:top_row),
                     c(bottom_row:top_row),
                     top_row,
                     bottom_row)
    
    sub_cols <- list(left_col,
                     right_col,
                     c(left_col:right_col),
                     c(left_col:right_col))
    
    directions <- list("Left", "Right", "Top", "Bottom")
    
    mapply(function(r_, c_, d) {
      temp_style <- createStyle(border = d,
                                borderColour = border_col,
                                borderStyle = border_thickness)
      addStyle(
        wb_,
        sheet_,
        style = temp_style,
        rows = r_,
        cols = c_,
        gridExpand = TRUE,
        stack = TRUE
      )
      
    }, sub_rows, sub_cols, directions)
  }

# Function call example
OutsideBorders(
  wb_,
  sheet_ = 1,
  rows_ = 1:nrow(test_sheet),
  cols_ = 1:ncol(test_sheet)
)
