java - 将 POI 样式从工作表克隆到另一个工作表

Question

我有一个 XSSF 模板表我正在尝试基于模板创建 SXSSF 文件，我可以成功创建工作表，但是当我尝试将样式从旧工作表复制到新工作表时遇到问题

这是我的代码

FileInputStream templateFile = null;
XSSFWorkbook templateWorkbook = null;
XSSFSheet templateSheet = null;

templateFile = new FileInputStream(this.templateFilePath);
templateWorkbook = new XSSFWorkbook(templateFile);
templateSheet = templateWorkbook.getSheetAt(0);

SXSSFWorkbook sworkbook = new SXSSFWorkbook(this.largeReportCashRows);      
SXSSFSheet sworksheet = (SXSSFSheet) sworkbook.createSheet();


//Create styles
CellStyle newStyle = sworkbook.createCellStyle();
//style.setFillPattern(XSSFCellStyle.FINE_DOTS );
//style.setFillBackgroundColor(IndexedColors.RED.getIndex());
CellStyle oldCellStyle = templateSheet.getRow(0).getCell(0).getCellStyle();
newStyle.cloneStyleFrom(oldCellStyle);

//SOME CODE TO CREATE ROWS & CELLS IN THE new sheet "sworksheet"
Cell cell1;
cell1.setCellStyle(newStyle);

当我执行代码时，它会运行并生成工作表，但是当我打开它时，我收到一条错误消息，告诉我工作表已损坏，在告诉 Excel 修复它后。它已修复，但样式不起作用!

请帮忙

        //to get old cell style from a cell
        CellStyle oldCellStyle = sheet.getRow(0).getCell(0).getCellStyle();

        //to create a new sheet in which you want to use this style
        XSSFSheet sheet2 = workbook.createSheet("new2");

        row=sheet2.createRow(0);
        cell=row.createCell(0);
        cell.setCellValue("test");
        //to set old style to new cell
        cell.setCellStyle(oldCellStyle);

        FileOutputStream out1 = new FileOutputStream("D:\\test.xlsx");
        workbook.write(out1);
        out1.close();
