Answer 2

为了处理常规样式和数据，我们可以迭代每个单元格 但是如果我们有公式启用的单元格，不可编辑的单元格，合并单元格，那么这是更好的解决方案：
我尝试过像复印纸一样的东西，但它没有用 此外，我需要复制一张表格，其中有一些不可编辑的单元格和公式启用的单元格。

此解决方案对我有用：
1）复制整个工作簿
2）删除不必要的表格 3）将新表格添加到上面的书中

//input source excel file which contains sheets to be copied
file = new FileInputStream("C:\\SamepleTemplate.xlsx");
workbookinput = new XSSFWorkbook(file);

//output new excel file to which we need to copy the above sheets
//this would copy entire workbook from source
XSSFWorkbook workbookoutput=workbookinput;

//delete one or two unnecessary sheets, you can delete them by specifying the sheetnames
workbook.removeSheetAt(workbook.getSheetIndex(workbook.getSheet(" your sheet name ")));

//if you want to delete more sheets you can use a for to delete the sheets
for (int index=0;index<=5;index++)
{
   workbook.removeSheetAt(index);
}

//To write your changes to new workbook
FileOutputStream out = new FileOutputStream("C:\\FinalOutput.xlsx");
workbookoutput.write(out);
out.close();
