Description

format_table_body turns list-shaped table_data into the Markdown table that goes into the table prompt (query.py, modalprocessors.py) and the table chunk (processor.py). That is the shape non-MinerU parsers and insert_content_list callers pass. It joined str(cell) with " | ", so four ordinary cell values broke the table:

format_table_body([["Name", "Qty", "Note"], ["pen", None, "a|b"], ["ink", 3, "two\nlines"], ["cap"]])

main:                          this PR:
| Name | Qty | Note |          | Name | Qty | Note |
| --- | --- | --- |             | --- | --- | --- |
| pen | None | a|b |            | pen |  | a\|b |
| ink | 3 | two                 | ink | 3 | two lines |
lines |                         | cap |  |  |
| cap |

• An empty cell (None) read as the word "None".
• A pipe inside a cell started an extra column.
• A line break inside a cell ended the row, so lines | became a stray line.
• A row shorter than the header stayed short.

Related Issues

None found. The list-of-lists rendering came with the content-list alias handling.

Changes Made

• raganything/utils.py: a new _table_cell renders each cell. None becomes empty, | becomes \|, and a line break becomes a space. format_table_body now pads every row to the widest row. String table bodies and other shapes are unchanged.
• tests/test_content_list_alias_handling.py: test_table_rows_keep_their_cells uses the table above. The existing [["A", "B"], ["C", "D"]] assertion still holds.

Checklist

• Changes tested locally
• Code reviewed
• Documentation updated (if necessary)
• Unit tests added (if applicable)

Additional Notes

• The new test fails on main and passes here. Full pytest tests/ on Python 3.12: 899 passed.
• pre-commit run (ruff-format, ruff, whitespace hooks) on both files: all hooks pass.
• Side note: test_content_list_alias_handling.py cannot be run on its own on main. Its stub for raganything.parser has no HTML_FILE_EXTENSIONS, which processor.py imports since fix(parser): require Docling for HTML instead of converting it with LibreOffice #418. The stub is only installed when nothing imported the real module first, so the full suite passes and CI stays green. I left that alone here.
