最近在写Excel导出功能，需要合并多行，优化过程分为了上下两篇，上篇是基础篇，下篇是优化篇，优化是利用java8 提供的新功能，方法可以作为参数传递！
这是导出的Excel的样式
优化的内容，仅涉及下面单元格内容数据填充，下面的几个方法。
待优化方法，结构基本相似，当currRow < maxRow的时候，是需要合并单元格的，否则不需要合并，所以每个方法就分了需要合并单元格和不需要合并单元格两种情况去考虑。头部的一段是判断实体或者数组是否为空，为空的话，设置单元格的值为""(默认值)。待优化的方法分为两类，一类是往Excel中写单行，参数传的是Entity，一类是往Excel中写多行，参数传的是List。单行的情况
多行的情况：
下面是具体代码，可以浏览一下。代码单独跑是跑不起来的，但是可以观思路
