easyExcel 读取有合并单元格数据

读取

 EasyExcel.read(new File("C:\\Users\\Lenovo\\Desktop\\fsdownload\\设备图纸.xlsx"),new MergeAwareListener(dataMap -> {for (int i = 0; i < dataMap.size(); i++) {if (i == 0){continue;}//每列的数据Map<Integer, String> map = dataMap.get(i);System.out.println( map);}})).charset(StandardCharsets.UTF_8).excelType(ExcelTypeEnum.XLSX).extraRead(CellExtraTypeEnum.MERGE).sheet(0).headRowNumber(0).doRead();
