excel 转pdf html 图片显示问题

1）xcel中图片不显示问题，poi官方给的资料，我找了，发现不行，网上查了资料，但是是只能显示图片，但是大小不行，而且excel转成html后，再转成pdf，遇到个问题，excel转后是以table，tr，td模式的，这样就会造成，图片显示小，不规矩问题，而且图片似乎在excel不是以表格形式存在的，而是以似乎另外一个图层，显示的，因此造成了这个图片不显示问题，解决方案，获取图片的左上坐标，右下坐标，在生成html的时候，把td
tr 使用rowspan
和colspan合并即可。
感谢 http://git.oschina.net/hopeZp/codes/zjsf63hcxvil8aowk5u7e98，里面绝大多数代码都是他的,我只加了，图片显示的 rowspan colspan代码

* @ClassName: PoiExcelToHtmlUtil
* @Description: TODO(poi转excel为html)
* @author liang
* @date 2016年5月5日 下午3:50:20
* 2017年5月19日，张鹏：添加隐藏行的过滤，修改excelToHtml入口参数，保证逻辑的正确性
* 2017年5月26日，张鹏：添加图片处理，当excel中包含图片时，先将图片保存到指定位置，后面在html代码中引用该图片，不同使用环境可修改保存位置，在web环境下，可指定到webapp下
* 2017年5月27日，张鹏：针对合并单元格后又隐藏了首行（此时下面的行列虽然可以显示正确的数据，但是poi无法读取到对应的value）的特殊类型excel，进行合并代码的重构
* 2017年5月27日，张鹏：边框全部使用黑色基本样式，解决合并后部分边框为灰色的问题；如果有特殊要求，可在dealStyle方法中解放原来的颜色获取方法
* 2017年6月5日，张鹏：样式处理方法dealstyle中，修改width属性的获取方式，解决由于合并单元格只计算单独宽度时造成的宽度计算错误的问题，并将原有的宽度转换为了pt单位，原有的px方式存在错误
* 2017年6月6日，张鹏：添加多sheet的excel转换方式，提供此类调用的一套接口

* @ClassName: PoiExcelToHtmlUtil
* @Description: TODO(poi转excel为html)
* @author liang
* @date 2016年5月5日 下午3:50:20
* 2017年5月19日，张鹏：添加隐藏行的过滤，修改excelToHtml入口参数，保证逻辑的正确性
* 2017年5月26日，张鹏：添加图片处理，当excel中包含图片时，先将图片保存到指定位置，后面在html代码中引用该图片，不同使用环境可修改保存位置，在web环境下，可指定到webapp下
* 2017年5月27日，张鹏：针对合并单元格后又隐藏了首行（此时下面的行列虽然可以显示正确的数据，但是poi无法读取到对应的value）的特殊类型excel，进行合并代码的重构
* 2017年5月27日，张鹏：边框全部使用黑色基本样式，解决合并后部分边框为灰色的问题；如果有特殊要求，可在dealStyle方法中解放原来的颜色获取方法
* 2017年6月5日，张鹏：样式处理方法dealstyle中，修改width属性的获取方式，解决由于合并单元格只计算单独宽度时造成的宽度计算错误的问题，并将原有的宽度转换为了pt单位，原有的px方式存在错误
* 2017年6月6日，张鹏：添加多sheet的excel转换方式，提供此类调用的一套接口
