Question

Answer 1

为了处理常规样式和数据，我们可以遍历每个单元格。
但是如果我们有启用公式的单元格、不可编辑的单元格、合并的单元格，那么这是更好的解决方案:
我试过像复印表格之类的方法，但没有用。
除此之外，我还需要复制一张工作表，其中还有一些不可编辑的单元格和启用公式的单元格。

这个解决方案对我有用:
1)复制整个工作簿
2)删除不需要的工作表 3) 将你的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();
