angular - 清晰度数据网格在使用内置字符串过滤器过滤数字时遇到问题

Question

我正在使用 Clarity 的数据网格来显示带有过滤和分页选项的表格。我的两列是嵌套对象，但是这两列的过滤器 - 看护人姓名和看护人代码不起作用；结果是一个空对象。过滤器在未嵌套的状态列上工作正常，因此我使用没有方括号的 clrDgField="status"。amount 也不起作用 - 这意味着输入数字时对象为空。*我刚刚意识到问题不在于嵌套对象；当您输入全名时，护理人员姓名列确实有效。似乎只有数字过滤器（如数量和代码）不起作用。*如果我将 Firestore 中的类型更改为字符串，它会起作用。我想知道这是不是唯一的方法。这是我的代码：模板
