这是模板excel：

，

但是导出数据之后就变成这样了：

求高手解决。

导出excel的方法如下：

public static Sheet export(Workbook workbook, ExportConfiguration exportConfiguration, ExportDataVo exportDataVo, int sheetIndex, int startIndex, int lIndex, String sheetName) throws Exception {
   Sheet sheet = workbook.cloneSheet(0);
   workbook.setSheetOrder(sheet.getSheetName(), sheetIndex);
   int list_data_row = exportConfiguration.getList_data_row();
   Boolean summry_bold = exportConfiguration.getSummry_bold();
   int add_row_mode = exportConfiguration.getAdd_row_mode();
   List dataList = exportDataVo.getDataList();
   Integer multiple = exportConfiguration.getMultiple();
   Integer space = exportConfiguration.getSpace();

   workbook.setSheetName(sheetIndex, sheetName);
   writeSheetHead(exportDataVo, sheet);
Object summryBean = null;
boolean unadd = true;
Font summryFont = null;

int count=0;
if(dataList !=null){
   for (int i=0, rowIndex=list_data_row; i<dataList.size(); i++, rowIndex++) {
   Object object = dataList.get(i);

   if (rowIndex > list_data_row && add_row_mode == 2) {
       sheet.shiftRows(rowIndex, rowIndex+2, 1, true, false);
   }
   Row row = sheet.getRow(rowIndex);
   if (row == null) {
       sheet.shiftRows(rowIndex, dataList.size(), 1);
       row = sheet.createRow(rowIndex);
       if (rowIndex > list_data_row) {
           row.setHeightInPoints(sheet.getRow(list_data_row).getHeightInPoints());
       }
   }
Field[] fieldArr = object.getClass().getDeclaredFields();
