评论具有使用Apche poi XSSFWorkbook创建的透明背景

Question

我正在尝试使用Apache poi XSSFWorkbook在.xlsm excel模板中添加注释，但是注释始终显示透明的背景色。有人知道如何操纵XSSFWorkbook的注释样式吗？ Apache poi：v3.15； excel扩展名：.xlsm; 操作系统：Mac

这就是我发现的内容：当前的模板样式可能会影响XSSFWorkbook的注释样式，因为在创建全新的工作表或模板时，添加注释的效果很好。...但是我确实需要在所需的现有工作表中添加注释。

import org.apache.poi.ss.usermodel.ClientAnchor.AnchorType
import org.apache.poi.ss.usermodel._
import org.apache.poi.ss.util.{CellRangeAddress, CellReference}
import org.apache.poi.util.Units
import org.apache.poi.xssf.usermodel._

         val file = WorkbookFactory.create("worksheet.xlsm")
    private def setComment(file: Workbook) : Workbook = {
          //get sheet
          val currentSheet = file.getSheet("Sheet1")
          val rowInfo = currentSheet.getRow(2)
          val cell = rowInfo.getCell(3)
          //begin adding comment
          val factory = file.getCreationHelper()
          val drawing = cell.getSheet.createDrawingPatriarch()
          //create comment box
          val anchor = factory.createClientAnchor()
          //locate comment
          anchor.setCol1(cell.getColumnIndex + 1 )
          anchor.setRow1(cell.getRowIndex+1)
          anchor.setCol2(cell.getColumnIndex + 5 )
          anchor.setRow2(cell.getRowIndex + 4)
          val comment1 = drawing.createCellComment(anchor)
          val str = factory.createRichTextString("this is a comment")
          comment1.setString(str)
          cell.setCellComment(comment1)
          file
     }

将鼠标悬停在不透明的背景注释上时，预期结果应该是正常的黄框注释
