问题描述
每当我使用输入参数 fileLookup 调用 java 网络服务 (HTTP GET) lookupId 时，它都会以如下所示的数组形式返回响应。
[
"1224,First_File.docx,null,458,null","1225,Second File.js,test for description,15514,778,"1226,Third_File.pdf,876,null"
]
收到的响应值对应于以下字段。
File id File Name Description user Id File Version
例如，在1224,null的情况下，1224是File id，First_File.docx是File Name，null是{{1} },Description 分别为 458 和 user Id 分别为 null。
我想显示一个primereact数据表，它将显示在表中的东西之上。但是，我发现的大多数示例都使用 JSON 数据。例如，this sandbox example。就我而言，由于我没有 JSON 对象形式的数据，我是否应该首先考虑将上述数据转换为 JSON，以便我可以将其提供给数据表或其他任何可以实现相同目的的数据？
