【场景】生成word合同，套打不支持
【原因】按照既有框架无法实现，所有逻辑均由控件+位置渲染实现，而非合同样式
【案例】自定义word模板，自实现word合同生成；获取单据头、单据体、基础资料的子字段
(备注：代码仅做参考，部分代码需要根据自己的场景实现)
<1>word模板定义
其中字段占位符使用实现；
```config
<$txt_fieldKey$>
<$txt_basefieldKey.subprop$>
```
<2>插件代码
图片、表格逻辑没有实现，可参考[npoi word模板](https://www.cnblogs.com/zhoushangwu/p/15603425.html)
