 如果是多个sheet页制作,需要多个  WriteSheet 信息

WriteSheet writeSheet0 = EasyExcel.writerSheet(0).build();   信息,You can change the numbers in it,多个sheetPage parameter information is not public,

代码如下

        WriteSheet writeSheet0 = EasyExcel.writerSheet(0).build();
        //开启自动换行,Word wrap means writing one line at a timelistData is regenerated with a blank line,此选项默认是关闭的,需要提前设置为true
        FillConfig fillConfig = FillConfig.builder().forceNewRow(Boolean.TRUE).build();
        FillConfig fillConfig2 = FillConfig.builder().direction(WriteDirectionEnum.HORIZONTAL).build();
        //excelWriter.fill(paramValueMapListNew, fillConfig, writeSheet);
        excelWriter.fill(new FillWrapper("user", paramValueMapListNew), fillConfig, writeSheet0);
        excelWriter.fill(new FillWrapper("site", paramValueMapListNew), fillConfig, writeSheet0);
        excelWriter.fill( paramValueMapListNew, fillConfig2, writeSheet0);

        Map<String, Object> map1 = new HashMap<>();
        map1.put("title", "Drug recall record sheet");
        map1.put("total", 1000);
        map1.put("time", "2022年07月22日13:28:28");
