easyexcel多行不同的表头导出（多表格不同表头）

一、效果展示

在这里插入图片描述

二、代码

/*** 导出月度报表数据信息*/@ApiOperation(value = "导出月度报表数据信息")@Log(title = "导出月度报表", businessType = BusinessType.EXPORT)@RequestMapping("/exportMonthChart")public void exportMonthChart(HttpServletResponse response) {try {tableWrite(response,input);} catch (IOException e) {e.printStackTrace();}}public void tableWrite(HttpServletResponse response) throws IOException {MonthChartOutput output = lsDeviceInfoService.monthChart(input);WriteSheet writeSheet = EasyExcel.writerSheet("设备月度报表").needHead(Boolean.FALSE).build();// 这里必须指定需要头，table 会继承sheet的配置，sheet配置了不需要，table 默认也是不需要WriteTable writeTable0 = EasyExcel.writerTable(0).needHead(Boolean.TRUE).head(ExportVO.class).build();WriteTable writeTable1 = EasyExcel.writerTable(1).needHead(Boolean.TRUE).head(ExportVO.class).build();WriteTable writeTable2 = EasyExcel.writerTable(2).needHead(Boolean.TRUE).head(DemoData.class).build();// 生成无表头的内容List<List<String>> headList = Lists.newArrayList();headList.add(Lists.newArrayList("自定义表头1","自定义表头2","自定义表头3"));// 生成有表头的内容List<ExportVO> list = Lists.newArrayList();for (int i = 1; i < 10; i++) {list.add(ExportVO.builder().heat1("第"+i+"行内容").heat2("第"+i+"行内容").heat3("第"+i+"行内容").heat4("第"+i+"行内容").heat5("第"+i+"行内容").build());}String fileName = URLEncoder.encode("销售表现趋势分析-"+ System.currentTimeMillis()+".xlsx", "UTF-8");response.setCharacterEncoding("UTF-8");response.setHeader("content-Type", "application/vnd.ms-excel");response.setHeader("Content-Disposition", "attachment;filename=" + fileName);response.setHeader("filename", fileName);ExcelWriter excelWriter = EasyExcel.write(response.getOutputStream()).build();// 第一次写入excelWriter.write(headList, writeSheet, writeTable0);// 第二次写入会创建头，然后在第一次的后面写入数据excelWriter.write(list, writeSheet, writeTable1);excelWriter.write(data(), writeSheet, writeTable2);excelWriter.finish();}private List<DemoData> data() {List<DemoData> list = ListUtils.newArrayList();for (int i = 0; i < 10; i++) {DemoData data = new DemoData();data.setString("字符串" + i);data.setDate(new Date());data.setDoubleData(0.56);list.add(data);}return list;}

实体DemoData 代码：

@Getter
@Setter
@EqualsAndHashCode
public class DemoData {@ExcelProperty("字符串标题")private String string;@ExcelProperty("日期标题")private Date date;@ExcelProperty("数字标题")private Double doubleData;/*** 忽略这个字段*/@ExcelIgnoreprivate String ignore;
}

实体DemoData 代码：

@Data
@Builder
@AllArgsConstructor
@NoArgsConstructor
@HeadRowHeight(18)
@ContentRowHeight(15)
@ColumnWidth(16)
public class ExportVO {@ExcelProperty("表头1")private String heat1;@ExcelProperty("表头2")private String heat2;@ExcelProperty("表头3")private String heat3;@ExcelProperty("表头4")private String heat4;@ExcelProperty("表头5")private String heat5;
}
