 * @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
