Running pytest --doctest-modules pyranges in a narrow or headless environment can hide table columns and fail doctests, even though the values are unchanged. GitHub CI masked this because the formatter forces a 250-column width whenever GITHUB_ACTIONS is set.

Set COLUMNS=250 in an autouse fixture restricted to doctest items. Ordinary tests and normal library display keep their existing settings. Run CI doctests with GITHUB_ACTIONS unset and an initial 80-column width so the GitHub-only workaround can no longer hide this regression.

Validation:

• Reproduced the reported GenomicFeaturesMethods.tss failure at COLUMNS=80 with GITHUB_ACTIONS unset.
• After the fix, all 87 doctests and 40 unit tests pass under those conditions on both pandas 2.3.3 and 3.0.6.
• Confirmed that COLUMNS=250 pytest --doctest-modules pyranges is a working workaround for the existing 0.1.6 source (87 passed).
• Black, isort and git diff --check pass for the change.
