rowalign controls the vertical alignment of cell text in multiline rows, but it is not mentioned in the tabulate() docstring or the README — the only references in the repo are the signature check in test_api.py and test_fancy_grid_multiline_row_align. This adds a 'Row alignment' section to the tabulate() docstring describing the accepted values ("top" (default), "center", "bottom"), the single-string (all rows) vs per-row list forms (None in the list means the default for that row), that single-line rows are unaffected, and that it only takes effect in formats that draw a line between rows (e.g. grid, fancy_grid). Scope: documentation only, one file (tabulate/__init__.py), no behaviour change. No >>> examples were added, since the repo runs pytest with --doctest-modules. Tests: full suite python -m pytest -q --ignore=benchmark — 339 passed, 44 skipped, 0 failed, identical to the clean-base run before the change. --doctest-modules tabulate/__init__.py alone: 16 passed.
