例子
在这里插入图片描述
代码

StorageService localStorageService = storageFactory.getLocalStorageService();
        String path = "";
        // 文件信息
        String dateTime = DateUtils.formatTimestampToString(new Date());
        String title = "xxx统计";
        String fileName = StringUtils.dbc2sbcCase(title) + "_" + dateTime + EXCEL_SUFFIX;

        File file = null;
        ExcelWriter excelWriter = null;
        WriteSheet writeSheet = null;
        int num = 0;
        try {
            file = localStorageService.newTempFile(fileName);
            excelWriter = EasyExcel.write(file.getPath()).build();

            writeSheet = EasyExcel.writerSheet(title).sheetNo(0).registerWriteHandler(new CustomizeColumnWidth()).build();

            // 写入数据
            List<List<String>> headList = new ArrayList<>();
            headList.add(Lists.newArrayList(title,"数据1"));
            headList.add(Lists.newArrayList(title,"数据2"));
            headList.add(Lists.newArrayList(title,"数据3"));
            //数据
            List<List<String>> objects = new ArrayList<>();
            objects.add(Lists.newArrayList("123","321","222"));

            WriteTable writeTable = EasyExcel.writerTable(num)
                    .head(headList)
                    .registerWriteHandler(ExcelUtils.getStyleStrategy()).build();
            excelWriter.write(Lists.newArrayList(objects), writeSheet, writeTable);
            num++;

        } catch (Exception e) {
            e.printStackTrace();
        }
        if (excelWriter != null) {
            // 写入数据
            List<List<String>> headList = new ArrayList<>();
            String tableTitle = "第二个表题";
            headList.add(Lists.newArrayList(tableTitle,"姓名"));
            headList.add(Lists.newArrayList(tableTitle,"年龄"));
            headList.add(Lists.newArrayList(tableTitle,"性别"));
            //数据
            List<List<String>> objects = new ArrayList<>();
            objects.add(Lists.newArrayList("admin","18","男"));
            objects.add(Lists.newArrayList("admin2","19","男"));

            WriteTable writeTable = EasyExcel.writerTable(num)
                    .head(headList)
                    .registerWriteHandler(ExcelUtils.getStyleStrategy()).build();
            excelWriter.write(Lists.newArrayList(objects), writeSheet, writeTable);
            num++;
            try {
                excelWriter.finish();
                path = FileUtils.uploadFile(file, fileName, orgId, userId);
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        // 生成文件路径
        return path;

重点:

需要合并列的字段重复设到表头

List<List<String>> headList = new ArrayList<>();
            headList.add(Lists.newArrayList(title,"数据1"));
            headList.add(Lists.newArrayList(title,"数据2"));
            headList.add(Lists.newArrayList(title,"数据3"));
