使用oDataModel的ui5 sap.m.table动态绑定

Question

我在表格和数据方面苦苦挣扎，让我给您一些上下文信息，我使用的是1.72.3版本，我的应用程序是Nginx中托管的独立应用程序，所有代理均已安装到位并且可以正常工作。

我有一个像工作清单的视图（一个表的视图），我需要使用过滤器查询后端，但是JSONModel不允许，所以我的想法很简单

• 我在JSONModel中创建了一个名为“ salesOrders”的道具
• 使用事件attachPatternMatched，我使用oDataModel调用了后端
• 我通过调用oDataModel的结果设置了属性“ salesOrders”
• 我将表格绑定到属性

我放置了所有代码，但我在屏幕上获得的最佳结果是

这是视图中我的表的定义。
