What

tablefmt="moinmoin" and tablefmt="textile" write cell and header values raw, so a literal pipe in the content silently splits the cell — the same class as the mediawiki problem (#499), with these two formats' own separators:

>>> print(tabulate.tabulate([["x | y", "a || b"]], tablefmt="moinmoin"))
||<style="text-align: left;">  x | y    ||<style="text-align: left;">  a || b  ||

|| is the cell separator in MoinMoin tables, so a || b becomes three cells and the style attribute lands on a phantom cell. In textile, | is the separator, so x | y splits in two. Rendered on a real MoinMoin wiki or through a textile converter, the data is silently corrupted.

Fixes #501

Fix

Write literal pipes as | in the values of both formats — MoinMoin and Textile both pass numeric character references through and render them as the literal character:

• _moin_row_with_attrs escapes cell values (header cells included, they go through the same function).
• _textile_row_with_attrs escapes data-row values, and the textile header row now uses the existing DataRow.escape_map machinery ({r"|": r"|"}) — the same mechanism GITHUB_ESCAPE_RULES uses for the pipe/github formats.

Values without pipes are byte-identical to before; the existing test_moinmoin* pins are unchanged.

Verification

Two new tests (test_moinmoin_escapes_pipes, test_textile_escapes_pipes) fail on master and pass with this change. Full suite: python3 -m pytest test/ → 351 passed, 17 skipped, zero failures.
