2. Empty records are now correctly displayed if inside of another record
list or table:

lists/tables:

# User-Facing Changes

`table` command now displays empty records and lists like a table with
text and correctly displays empty records inside tables and lists.

New behavior of displaying empty lists and records can be disabled using
`table.show_empty` config option.

# Tests + Formatting

Don't forget to add tests that cover your changes.

Make sure you've run and fixed any issues with these commands:

- `cargo fmt --all -- --check` to check standard code formatting (`cargo
fmt --all` applies these changes)
- `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used -A
clippy::needless_collect` to check that you're using the standard code
style
- `cargo test --workspace` to check that all tests pass

# After Submitting

If your PR had any user-facing changes, update [the
documentation](https://github.com/nushell/nushell.github.io) after the
PR is merged, if necessary. This will help us keep the docs up to date.
