通过poi导出形如以下的复杂excel：
此excel里左边和右边的用户可以自由选择是否导出这几列，中间的题型有单选、多选、填空、排序
这是详情表，还有分值表如下：
占比表如下：
我自己写了个针对上面的工具类：

还有两个需要用到的dto：
import lombok.Builder;
import lombok.Data;
import java.util.List;
@Data
@Builder
public class CellModel {
// 列对应的key
String colsKey;
// 列对应的名字
String cellName;
// 列所在的起始位置
int columIndex;
// 列合并数 大于1代表合并
int colspan;
// 行合并数据，大于代表合并
int rowspan;
// 列合并数据 比如 A。满意， B.不满意
List<String> childCellList;
//列合并数据简写 如 A ,B
List<String> childQz;
String tiltleType;
}
还有：
import lombok.Data;
@Data
public class CellValueModel {
// 存放key
private String colsKey;
// 存放值
private String colsValue;
}还有：
import lombok.Builder;
import lombok.Data;
@Data
@Builder
public class RowDataModel {
private String id;
private String items;
private String userName;
private String phone;
private String email;
private String province;
private String city;
private String country;
private String address;
private String answer;
private String sourceTool;
private String sourceWay;
private String isLucky;
}还有：
import lombok.Builder;
import lombok.Data;
@Builder
@Data
public class TitleAnswerModel {
private String aswerId;
private String titleQid;//1
private String theAnswer;//A
private String theAnswerName;//是
private String allowNull;//N
private String maxLength;
}具体的xml文件的sql就不贴了，涉及到公司的代码，以上就是我写的复杂报表的导出功能。
