It is not impossible.
As said you can search for the index.
e.g
[{"id":"fcd9ceaf8abf44e4","type":"inject","z":"d1395164b4eec73e","name":"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"[{\"id\":1,\"test\":\"one\"},{\"id\":2,\"test\":\"two\"}]","payloadType":"json","x":210,"y":5680,"wires":[["31850bca664e6129"]]},{"id":"31850bca664e6129","type":"change","z":"d1395164b4eec73e","name":"","rules":[{"t":"set","p":"table_data","pt":"flow","to":"payload","tot":"msg","dc":true}],"action":"","property":"","from":"","to":"","reg":false,"x":230,"y":5640,"wires":[["7f4163ee549d9273"]]},{"id":"7f4163ee549d9273","type":"ui-table","z":"d1395164b4eec73e","group":"9d83cd8b3d5ee33c","name":"","label":"","order":1,"width":0,"height":0,"maxrows":0,"passthru":false,"autocols":false,"showSearch":true,"selectionType":"click","columns":[{"title":"","key":"test","keyType":"key","type":"text","width":"","align":"start"}],"mobileBreakpoint":"sm","mobileBreakpointType":"defaults","action":"replace","x":410,"y":5660,"wires":[["1f3fe7ccad345bc7"]]},{"id":"1f3fe7ccad345bc7","type":"function","z":"d1395164b4eec73e","name":"function 1","func":"const table_data = flow.get(\"table_data\") ??

If you store you data as an object, with the row id as the name the search would be easier. and very simple to convert to array for the table data.
e.g
