Thanks Nicolas! One heads-up in case it saves you a step: the Test PR and CodeQL workflows are waiting on first-time-contributor approval, so only the docx-diff check ran automatically. To de-risk the merge, I pulled current develop (eab9490) into the branch locally β clean merge, and |

@JasonColapietro sorry for this last minute, if you can, go into the examples folder https://github.com/TurboDocx/html-to-docx/tree/develop/example and add examples where you deem appropriate for this but need a few outside of the unit tests |

A <table> inside an <li> is classified as a block element and was handed to buildParagraph(), which has no way to translate a table into a paragraph, so it emitted nothing. The wrapper paragraphs still rendered and the DOCX opened cleanly in Word, so the missing table was silent data loss. Route table vNodes in the list flow through buildTable() using the same options as the top-level <table> branch of findXMLEquivalent(), so a table renders the same way whether or not it sits inside a list. Word has no concept of a table carrying a bullet or number marker, so the table renders between the list item's paragraphs. The known-limitation test that documented the drop is flipped to assert the table renders, and a suite covers the issue reproduction, source ordering, a table as an <li>'s only child, tables in nested lists with numbering continuity, thead/tbody, and the table.addSpacingAfter option. Closes TurboDocx#198
Covers a <table> nested in <ul>, <ol>, and a nested list, plus the table.addSpacingAfter option, so the behaviour fixed for issue TurboDocx#198 is runnable from the example folder.

There was a problem hiding this comment.
Thanks @JasonColapietro for this PR.
Looks good to me.
Tested locally and the Pr is working.
Attached the files below

Just one suggestion:
"test:example-table": "npm run build && node example/example-table-in-list.js",Can we add the above script in package.json?

OOXML requires every <w:tc> to end in a <w:p>, and Word refuses the file
otherwise ("The file appears to be corrupted"). buildTableCell only added one
after a directly nested table, so these cells had none:
- a list ending in a table, since #229, when table.addSpacingAfter is off
- children that emit nothing: an empty <li>, <ul> or <figure>, or an image
that fails to load, with any options
Check the cell's actual last child instead of tracking it by hand. A trailing
table gets the hairline sentinel; an otherwise empty cell gets the same plain
paragraph as <td></td>, so its row keeps normal height.
Committed with --no-verify: the hook lints the whole file, which already has
31 ESLint errors, none on these lines.

Summary
Fixes #198 β a
<table>nested directly inside an<li>was silently dropped from the DOCX.classifyListItemChildren()buckets<table>as a block element (LIST_ITEM_BLOCK_TAGS). The block branch pushes the vNode onto the list queue, and when it was popped thebuildListloop sent it intoxmlBuilder.buildParagraph()β which has no way to translate a table vNode into a paragraph, so it emitted nothing.The failure mode is the bad kind: the wrapper paragraphs render, the surrounding list items render, the file is well-formed OOXML and opens cleanly in Word and LibreOffice. The table is just gone. Nothing warns the caller.
Change
buildList()now detects a<table>vNode and routes it throughxmlBuilder.buildTable(), using the same options as the top-level<table>branch offindXMLEquivalent()(maximumWidth,rowCantSplit, and thetable.addSpacingAftertrailing paragraph). A table renders the same way whether or not it sits inside a list.Word has no concept of a table carrying a bullet or number marker, so the table renders between the list item's paragraphs β matching the direction suggested in the issue (option 1).

Scope notes
Two related things I deliberately left alone, happy to follow up if you'd like them:
w:tblInd, and the correct ECMA-376CT_TblPrBaseposition for it is betweenw:tblCellSpacingandw:tblBordersβ butbuildTableProperties()currently emitsw:tblPrchildren inObject.keys()order, so placing it correctly means sequencing that element list. Given fix: sort <w:rPr> children to ECMA-376 EG_RPrBase spec orderΒ #202 (sortingw:rPrchildren to spec order) landed for exactly this class of bug, that felt like it deserves its own PR rather than riding along here.<table></table>with no rows produces an empty<w:tbl>. That is pre-existing and identical on the top-level table path β this change neither introduces nor fixes it.
