java-ee - java导出excel，修改写死界面的内容

我现在想修改导出Excel的部分界面。
下图是现在的界面，左边的使用说明是写死的，数据源是动态生成的，我现在只需要修改使用说明就好了。

这个是修改后变成的样子

部分后端代码

 private ExcelExport prepayExport(List list) {
        ExcelExport excelExport = new ExcelExport();
        excelExport.setSheetName(SeaxConstants.EXCEL_SHEET_NAME_COMPANY);
        excelExport.setHeaders(HEADERS);
        excelExport.setGetterMethodName(GETTER_METHOD_NAME);
        excelExport.setColumnWidth(COLUMN_WIDTH);
        excelExport.setDataset(list);
        excelExport.setList(InventoryExcelDescribe.getList());//得到使用说明的界面

        return excelExport;
    }
    

InventoryExcelDescribe类：

 ONE(1,"xxxx"),
TWO(2,"xxxx"),
THREE(3,"xxx"),
FOUR(4,"xxx"),
FIVE(5,"xxx"),
SIX(6,"xxx"),
SEVEN1(7,"  xxx黄色标示提醒"),
SEVEN2(8,"   xxx绿色标示提醒；"),
SEVEN3(9,"   xxx红色标示提醒"),
SEVEN4(10,"  xxx"),
SEVEN5(11,"  xxx"),
EIGHT(12,"xxx"),
NINE(13,"xxx");

    private String name;
    private int code;
      public static List getList() {
            List list = new ArrayList<>();
            for (InventoryExcelDescribe em : InventoryExcelDescribe.values()) {
                EnumObj obj = new EnumObj();
                obj.setId(em.getCode());
                obj.setName(em.getName());
                list.add(obj);
            }
            return list;
        }

那么我现在这么在原来的基础上加上3个单元格(7.8.9右边的单元格)，且各自都有背景色(固定位置的)？
