Initial Table View snapshot tests; optional Docker and VSCode configs

[mathiscode]

This PR resolves #1871 and resolves #1872 by adding snapshot test cases for Table View.

Also included is a docker-compose.yml to allow easy running, debugging, and testing with Docker to support a more dynamic development experience since port 3000 is the default for a lot of frameworks and can often already be bound. A .vscode/launch.json is also included for real-time debugging with VSCode. These are optional and shouldn't affect anyone's current workflow.

To use Docker, run npm run start:docker or docker compose up and connect as normal.
