CJK and emoji glyphs render as two terminal cells but JS String#length and the model's own padding count them as one, so any markdown table with Chinese / Japanese / Korean cells drifts right per row when a real terminal renders it. Both surfaces fix this with a display-cell width measurement (wcswidth on the Python side, stringWidth on the TUI side). Changes: - agent/markdown_tables.py: new helper. realign_markdown_tables(text) detects markdown table blocks (header + |---| divider) and rewrites the row padding using wcwidth.wcswidth so every pipe and dash lines up across rows. No-op on text without tables. - cli.py: hook the helper into _render_final_assistant_content for strip / render modes (raw passes through untouched), and into the streaming line emitter so live token-by-token rendering also produces aligned tables. A small two-buffer state machine in _emit_stream_text holds table rows until the block ends, then flushes them through the realigner so all rows pad to a single per-column width. - ui-tui/src/components/markdown.tsx: renderTable now uses stringWidth (Bun.stringWidth fast path + East-Asian-width-aware fallback, already memoised in @hermes/ink) instead of UTF-16 String#length for both column-width measurement and per-cell padding. Drops the comment that documented the bug as a deliberate limitation. Validation: - New tests/agent/test_markdown_tables.py (11): every rebuilt block shares pipe column offsets across rows for pure CJK, mixed CJK+emoji, ragged-row, and multi-table inputs. - Updated tests/cli/test_cli_markdown_rendering.py: the existing strip-mode test asserted exact whitespace; rewritten to assert the alignment contract (cell content survives + every rendered row shares pipe offsets). - New ui-tui markdown.test.ts case (1): rendered column-2 start offset is identical for the header + every body row, including the CJK row that drifted before the fix. - Live: hermes chat -q with the user-reported screenshot prompt now produces a perfectly aligned table on the wire (header, divider, 4 body rows including '通义千问', all pipes at identical columns).
