我有一种情况,我将阅读多行,并在一些逻辑后,我需要在Excel工作表中写行。我正在使用Apache POI来实现此目的。但是,我面临的问题是,只有最后一行(来自循环)被写入Excel
有人可以帮我解决这个问题或提供一些代码片段吗?

Workbook wb = new XSSFWorkbook(); //or new HSSFWorkbook();
Sheet sheet = wb.createSheet();
Row row = sheet.createRow(2);
Cell cell = row.createCell(2);
cell.setCellValue("Use \n with word wrap on to create a new line");
//to enable newlines you need set a cell styles with wrap=true
CellStyle cs = wb.createCellStyle();
cs.setWrapText(true);
cell.setCellStyle(cs);
//increase row height to accomodate two lines of text
row.setHeightInPoints((2*sheet.getDefaultRowHeightInPoints()));
//adjust column width to fit the content
sheet.autoSizeColumn((short)2);
FileOutputStream fileOut = new FileOutputStream("ooxml-newlines.xlsx");
wb.write(fileOut);
fileOut.close();
