expand_table setting doesn’t work.

[flying-sheep]

See scverse/scanpy#3964:

• I committed how it should format with that configuration: scverse/scanpy@edbb7b9
• But running pyproject-fmt makes these changes: scverse/scanpy@ba348f9

reproducer:

# /// script
# dependencies = [ "pyproject-fmt==2.12.0" ]
# ///

import sys
import difflib
from pyproject_fmt._lib import Settings, format_toml

settings = Settings(
    column_width=120,
    indent=4,
    keep_full_version=True,
    max_supported_python=(3, 14),
    min_supported_python=(3, 14),
    generate_python_version_classifiers=False,
    table_format="short",
    expand_tables=["project.optional-dependencies"],
    collapse_tables=[],
)

content = """\
[project]
name = "test"

[project.optional-dependencies]
a = [ "b", "c" ]
"""

sys.stdout.writelines(difflib.unified_diff(
    content.splitlines(keepends=True),
    format_toml(content, settings).splitlines(keepends=True),
    fromfile="input",
    tofile="output",
))

Can you please check the latest release and let me know how it goes?

Sure, thank you for attempting a fix!

1. there’s no v2.12.1 tag in https://github.com/tox-dev/pyproject-fmt, so I can’t use it as intended, but of course I can test manually:

2. project.optional-dependencies works now, but adding tool.ruff.lint.flake8-tidy-imports.banned-api to expand_tables still does nothing

3. for some reason, it removes the empty line between the project and project.optional-dependencies tables, is that intentional?
