读取 Excel(POI) 转 HTML
来源：互联网 发布：医疗器械软件描述范例 编辑：程序博客网 时间：2024/05/18 18:01
不知道大家有没有遇到把Excel 表格里面的内容输出到页面中的情况，反正小弟最近遇到了这种需求，就是Excel 里面有啥样式情况，那么网页中就是什么情况，由于Excel表格有很多，都在同一个文件夹下面，所以还需要遍历文件夹下所有的Excel 文件才行。
需求和图片效果请大家看下图：
这是Excel里面的样式以及内容，有单元格的合并，有边框，还有不同的颜色。
对应网页：
代码结构：可以建一个 java web 工程，也可以直接新建一个java 工程，我建的 java web 工程。
