【场景】套打数据表格动态列，在表单模型和列表模型的实现差异
【案例】实现采购订单，单个单据的动态列套打、连续套打的动态列套打、以及合并套打的动态列套打
<1>单个单据的动态列套打
[套打数据表格动态列](https://vip.kingdee.com/article/78446215485965568?productLineId=1)
效果：
<2>连续套打的动态列
效果：
<3>合并套打的动态列
效果：
【实现逻辑】
实现差异：
<1>在列表插件中，需要知道当前任务对应的单据内码，因此需要知道打印任务列表；
<2>同时获取尺码数据部分，需要自行加载单据数据包获取（列表不一定有）
<3>针对合并套打，需要把多个单的尺码数据全部合并一起算
<4>如果支持连续套打所选分录，那么在计算尺码时需要根据列表选中行过滤（这个在这个帖子中没有实现，但是不复杂）
记录打印任务列表：
根据连续套打和合并套打，计算当前次是哪个单据或哪些单据：
列表插件获取尺码数据：
