java - 使用 Apache POI 删除 Excel 工作表

Question

我必须从 Excel 文件中删除一张工作表。

这是我的代码片段：

FileInputStream fileStream = new FileInputStream(destFile);
POIFSFileSystem fsPoi = new POIFSFileSystem(fileStream);

HSSFWorkbook workbook = new HSSFWorkbook(fsPoi);

int index = 0;

HSSFSheet sheet = workbook.getSheet("Setup");
if(sheet != null)   {
    index = workbook.getSheetIndex(sheet);
    workbook.removeSheetAt(index);
}
return destFile;

在此之后，我得到了与我通过的完全相同的工作簿，而没有删除“设置”表

帮我解决这个问题。任何帮助，将不胜感激

Answer 1

编辑工作簿后，您需要重新编写它。试试这个：-

FileOutputStream output = new FileOutputStream(destFile);
workbook.write(output);
output.close();

编辑：- 写回后，您可以返回您的destFile.

Answer 2

private void removeOtherSheets(String sheetName, XSSFWorkbook book) {       
        for(int i=book.getNumberOfSheets()-1;i>=0;i--){
            XSSFSheet tmpSheet =book.getSheetAt(i);
            if(!tmpSheet.getSheetName().equals(sheetName)){
                book.removeSheetAt(i);
            }
        }       
}

使用 Apache POI 删除工作表

//Open file
  FileInputStream inputStream = new FileInputStream(new File(filePath));
  XSSFWorkbook workBook = new XSSFWorkbook(inputStream);

//Delete Sheet
  workBook.removeSheetAt(resultWorkbook.getSheetIndex("SheetToBeDeleted"));

//Save the file
  FileOutputStream outFile =new FileOutputStream(new File(filePath));
  workBook.write(filePath);
  outFile.close();
