poi替换模板标签为图片

在问答频道看到有人求poi模板替换图片的需求，百度一下，网上没有合适的方案，一时手痒，自己动手写了一个。本文参考了http://www.it165.net/pro/html/201108/451.html的方法，进行了部分修改，可以替换word2007的表格中的标签为图片，先看效果：





，再看代码

好像只能替换整行，如果是一行中有其他数据，只替换行中某个位置就不行啊

zykai029 写道

doc.addPicture(is, doc.PICTURE_TYPE_PNG);
这方法在哪

我用的 poi-3.7-20101029.jar，换下你的poi版本
