我在java中使用poi libary为我的应用程序将字符串放入excel文件中。 事情是我的一些字符串包含多行,当放入单元格时,只有一些信息是可见的,如第三列所示。 http://imgur.com/Iy7B2OY 我被迫双击单元格以查看应该呈现的信息。 有没有一种方法可以让信息像第三列的最后一行一样? 提前致谢。 编辑:这是执行转换作业的类的代码。

String filename = "C:\\Users\\daoudi\\Desktop\\FactureTest.xls" ;
HSSFWorkbook workbook = new HSSFWorkbook();
HSSFSheet sheet = workbook.createSheet("FirstSheet");
HSSFRow rowhead = sheet.createRow(0);


public conversion(List<String> nom , List<String> tel, List<String> abo, List<String> total) throws IOException{
    try{
        rowhead.createCell(0).setCellValue("Nom");
        rowhead.createCell(1).setCellValue("Telephone");
        rowhead.createCell(2).setCellValue("Abonnements");
        rowhead.createCell(3).setCellValue("Total");
    //HSSFCellStyle aligned = workbook.createCellStyle();
    //aligned.setAlignment(HSSFCellStyle.VERTICAL_JUSTIFY);


        for (int i=0;i<nom.size();i++){
        HSSFRow row = sheet.createRow(i+1);
        Cell cell = row.createCell(0);
        cell.setCellValue(nom.get(i));
            cell = row.createCell(1);
            cell.setCellValue(tel.get(i));
            cell = row.createCell(2);
            cell.setCellValue(abo.get(i));
            //cell.setCellStyle(aligned);
            cell = row.createCell(3);
            cell.setCellValue(total.get(i));
            //cell.setCellStyle(aligned);

    }

        sheet.autoSizeColumn((short)0);
        sheet.autoSizeColumn((short)1);
        sheet.autoSizeColumn((short)2);
        sheet.autoSizeColumn((short)3);
    FileOutputStream fileOut = new FileOutputStream(filename);
    workbook.write(fileOut);
    fileOut.close();

    } catch(IOException e) {
        e.printStackTrace();
    }

}

}

下面的工作代码示例

try {
        FileInputStream is = new FileInputStream(new File("C:\\Desktop\\ook.xls"));
        HSSFWorkbook wb = new HSSFWorkbook(is);
        String str = "111111111111111111111111111111111111111111111111111111111111111111111111111111111";
        HSSFSheet sheet = wb.getSheet("Sheet1");

        Row row =  sheet.createRow(0);
        Cell cell = row.createCell(0);
        Cell cell1 = row.createCell(1);

            CellStyle style = wb.createCellStyle(); 

            cell.setCellStyle(style); 
            cell.setCellValue(str); 

            CellStyle style2 = wb.createCellStyle(); 
            cell1.setCellStyle(style2); 
            cell1.setCellValue(str); 

            sheet.autoSizeColumn(0);
            sheet.autoSizeColumn(1);

        wb.write(new FileOutputStream(new File("C:\\Desktop\\ook.xls")));
    } catch (IOException e) {
        e.printStackTrace();
    }

我在第一行的前两列写了“str”。

此外,您还可以使用 autowrap ,以下示例:

try {
            FileInputStream is = new FileInputStream(new File("C:\\Desktop\\ook.xls"));
            HSSFWorkbook wb = new HSSFWorkbook(is);
            String str = "111111111111111111111111111111111111111111111111111111111111111111111111111111111111111";
            HSSFSheet sheet = wb.getSheet("Sheet1");

            Row row =  sheet.createRow(0);
            Cell cell = row.createCell(0);

                CellStyle style = wb.createCellStyle(); 
                style.setWrapText(true); 
                cell.setCellStyle(style); 
                cell.setCellValue(str);

            wb.write(new FileOutputStream(new File("C:\\Desktop\\ook.xls")));
        } catch (IOException e) {
            e.printStackTrace();
        }

结果:
