表单子表视图的使用方法

getDataOptions(): DataOptions {
  return {
    dynamicViews: {
      [F_BudgetAccount_refDocMappings(子表名字)]: 'viewName(视图名字)',
    },
  };
}

// 视图的数据
private viewData = observable.array([]);

// 查看态，渲染视图
onFormViewed(form: EntityForm<any>, disposers: IDisposer[]) {
  this.addView(disposers)
}

// 编辑态，渲染视图

  this.formPresenter.formController.addDynamicView(
    this.logicPath,
    'viewName',
    this.viewData,

  disposers.push(
    // 监听子表的数据变化
    reaction(
      () => {
        return this.form.select(this.logicPath).value.slice();
      },
      this.updateData,
      { fireImmediately: true },

// 将子表数据进行处理后赋值给视图数据
updateData = () => {
  const data = this.form.select(this.logicPath).value
  this.viewData.replace(data.filter());
