poi根据模板导出word（包含图片、动态生成表格、合并单元格）(亲测有效)

准备工作：

1.需要的jar(jar包在资源处已上传，可下载)

2.创建docx模板(doc不可以)

第一步：准备好jar(这里面的 ooxml-schemas-1.1.jar 大家可以尝试用poi-shemas-3.12-20150511.jar替换试试，但是偶尔会报java.lang.NoSuchMethodException: org.openxmlformats.schemas.wordprocessingml.x2006.....等错误，网络说poi-shemas-3.12-20150511.jar是简化版，需要用 ooxml-schemas-1.1.jar替换)

第二步：准备好docx模板（这里我写入了四个表格，根据您的需要制作，${date} 是段落部分， $符号不能没有，代码中需要判断替换的）

准备工作完成  下面是代码部分
