Columnar table view for `List` responses

gRPC standard `List` method output is rendered as one table per record, and records appear one after another mirroring `json` output passed through `jq`.

I would like to see columnar output.

What have I tried
1. searched for setting that would make this a table view.
2. I see that `populateResultContainer` is used to populate the `grpc-response-data .output-container` However that function is not wired up to anything in the latest code.
3. This function used to be called from $.ajax.Post.Done in v1.0.0

Please advise.
