#pragma mark返回多少个section

#pragma mark 设置分组标题内容高度
-(CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section{

return 40;
}

#pragma mark 设置每行高度（每行高度可以不一样）
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{
    if (indexPath.row == 0 && indexPath.section ==0) {
        return 80;
    }
    return 50;
}

#pragma mark 点击行
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
    NSLog(@"%ld====",(long)indexPath.section); NSLog(@"%ld-----",(long)indexPath.row);
}

在.h文件中需要定义几个常量:

{

    NSMutableArray *_arrLeft0;
    NSMutableArray *_arrLeft1;
    NSMutableArray *_arrLeft2;
    
    NSMutableArray *_arrRight0;
    NSMutableArray *_arrRight1;
    
    NSMutableArray *_arrTop;
    
    int  _cellLock;

}
