首先确保你don't mix sap.ui.commons and sap.m - 无论如何......
您正在尝试从表中删除一行，该表从JSONModel获取其数据。为了安全起见，你必须找到正确的＆＃34;行数据＆＃34;在删除它之前在模型中。您不能只使用表的选定索引，因为此索引与相应模型数据的索引不相关！因此，您需要做的是使用表API从属于所选行的模型中获取数据。之后你必须为这个＆＃34;数据＆＃34;找到正确的索引。在模型中，即通过循环模型数据并比较唯一标识符（在我们的例子中是OrderID）或使用一些更智能/更快的算法......一旦获得数据，只需将其从模型中删除...
这是一个工作示例，甚至可以用于排序（jsbin）
