Mimic BigQuery UI for nested and repeated columns

[dkapitan]

Description

I think it would be great if we could mimic the UI of BigQuery for nested and repeated columns:

Have been using BQ for a long time, until the Arrow/Parquet ecosystem finally arrived to handle nested and repeated columns. But I miss the UI, and haven't seen any of the IDEs mimic this.

Suggested solution

• struct columns are rendered with dot-notation; this will become a bit cumbersome for deeply nested structs
• repeated columns are grouped by row
