fix(super-converter): preserve cell-level SDT wrapping table cells (SD-3289) by caio-pizzol · Pull Request #3539 · superdoc-dev/superdoc

caio-pizzol · 2026-05-27T18:32:51Z

Preserves Word date pickers (and other content controls that wrap a single table cell) on DOCX import/export. The shape is <w:tr><w:sdt><w:sdtContent><w:tc>...</w:tc></w:sdtContent></w:sdt></w:tr> — ECMA-376 Part 1 §17.5.2.32, CT_SdtCell. The row importer previously filtered to direct w:tc children only, silently dropping the wrapped cell on import and from any subsequent export. Reported on IT-1119.

Row encoder recognizes both direct <w:tc> and cell-level <w:sdt>, routes the inner cell through the existing tc-translator, and preserves w:sdtPr / w:sdtEndPr on a new cellSdt attr (rendered: false, declared on both tableCell and tableHeader).
Row decoder re-wraps the exported <w:tc> in <w:sdt> when the attr is present, so the w:date subtree round-trips (fullDate, dateFormat, lid, storeMappedDataAs, calendar).
Tests: 11 unit tests plus a real table import/export round-trip integration test that drives defaultNodeListHandler and exportSchemaToJson against the IT-1119 OOXML shape with no translator mocks.

Out of scope, tracked as follow-ups: content-controls Document API exposure for cell-level controls (target-resolution.ts only finds structuredContent / structuredContentBlock); exact multi-cell CT_SdtContentCell grouping round-trip; analogous row-level SDT (CT_SdtRow) and w:customXml-wrapped row/cell drops at the same filter sites.

Review: row import normalize helper, row decode re-wrap, schema attr on both tableCell and tableHeader. Ignore: pre-existing TS errors elsewhere in tr-translator.js (net -1 from this change).
Verified: super-converter suite 2979/2979; tr/ handler dir 32/32 including the round-trip integration test; tsc errors in tr-translator.js 34 → 33.

…D-3289) Word date pickers and similar content controls that wrap a single table cell are stored in DOCX as `<w:tr><w:sdt><w:sdtContent><w:tc> ...</w:tc></w:sdtContent></w:sdt></w:tr>` (ECMA-376 Part 1 §17.5.2.32, CT_SdtCell). The row importer previously filtered to direct `w:tc` children only, silently dropping the wrapped cell on import and from any subsequent export. The row encoder now recognizes both direct `<w:tc>` and cell-level `<w:sdt>`, routes the inner cell through the existing tc-translator, and preserves `w:sdtPr`/`w:sdtEndPr` on a new `cellSdt` attr (rendered: false, declared on `tableCell` and `tableHeader`). The row decoder re-wraps the exported `<w:tc>` in `<w:sdt>` when the attr is present, so date metadata (fullDate, dateFormat, lid, calendar) round-trips. - Cell-level controls remain outside the content-controls Document API surface for v1. - Multi-cell `CT_SdtContentCell` wrappers import all cells defensively but drop wrapper metadata; exact multi-cell grouping is out of scope. - Adds 11 unit tests plus a real table import/export round-trip integration test covering the IT-1119 OOXML shape.

The MCP tools require permissions I don't have. I'll review based on the ECMA-376 spec from prior knowledge of the relevant sections.

Status: PASS

This PR correctly handles cell-level structured document tags. The key spec elements check out:

w:sdt as child of w:tr — ECMA-376 §17.4.79 (CT_Row) includes EG_ContentCellContent, which permits w:sdt (CT_SdtCell) as a legal sibling of w:tc. ✓ (spec)
CT_SdtCell structure — w:sdtPr (0..1), w:sdtEndPr (0..1), w:sdtContent (0..1, type CT_SdtContentCell). The code extracts these in the correct order. ✓
Multi-cell wrappers — The PR's comment notes that CT_SdtContentCell's content model (EG_ContentCellContent with maxOccurs="unbounded") does permit multiple inner w:tc. The defensive fallback (import all inner cells, drop wrapper metadata) is a reasonable choice given v1 doesn't model SDT-grouped cell ranges. ✓
w:date metadata — CT_SdtDate has w:fullDate as an optional ST_DateTime attribute, with child elements w:dateFormat (CT_String), w:lid (CT_Lang), w:storeMappedDataAs (CT_SdtDateMappingType with enum {text, date, dateTime}), w:calendar (CT_Calendar with ST_CalendarType enum including 'gregorian'). The test fixture nests these inside w:date correctly — not as direct w:sdtPr children, which would be wrong. ✓ (spec)
Export order — w:sdt → [w:sdtPr, w:sdtEndPr?, w:sdtContent] matches CT_SdtCell's sequence. ✓
w:tblW/w:tblLayout/w:tcW/w:gridCol in the integration fixture use standard attributes (w:w, w:type=dxa, etc.) — all spec-conformant.

The implementation treats the preserved sdtPr/sdtEndPr as opaque round-trip blobs, which is safe — no spec-defined attribute is being synthesized or stripped, so there's no risk of fabricating or losing values.

Linked issue: SD-3289: Preserve date content controls that wrap table cells

Status	Acceptance criteria	Notes
✅	Import recognizes a cell-level wrapping a single , unwraps it and preserves the wrapper's w:sdtPr / w:sdtEndPr as per-cell metadata (cellSdt)	The row normalizer extracts sdtPr/sdtEndPr and attaches cellSdt to the encoded tableCell when the wrapper contains exactly one w:tc.
✅	Inner is routed through the existing tc-translator with correct extraParams (columnIndex/columnWidth) rather than being dropped or processed incorrectly	The inner cell is passed to the existing tc translator and unit tests assert the translator was called with the expected extraParams.
✅	Export re-wraps a table cell carrying cellSdt in a envelope, reconstructing w:sdtPr (and w:sdtEndPr when present) so date subtree metadata (e.g. w:date fullDate and child elements) round-trips	Decoder replaces exported with containing preserved sdtPr/sdtEndPr and sdtContent; integration test verifies w:date attributes survive export and wrapped contains the date text.
✅	The date text is preserved in the editor model and the exported tree contains exactly one cell with the date (no duplication or accidental drop)	Integration test asserts the imported PM table has the date text in the correct cell and the exported OOXML contains a single wrapped cell with the date text.
✅	Multi-cell SDT wrappers are handled defensively (do not claim to round-trip multi-cell grouping) — inner cells are imported but wrapper metadata is not incorrectly applied	The normalizer drops wrapper metadata when sdtContent contains multiple w:tc children, emitting each inner cell without cellSdt, matching the PR's stated conservative behavior.

…SD-3289) The row encoder unwraps `<w:sdt><w:sdtContent><w:tc/></w:sdtContent></w:sdt>` into real cells, but `findTableCellAtColumn` (called from `handleTableCellNode` to mark vMerge continuations) still filtered to direct `<w:tc>` children of `<w:tr>`. As a result, a vertical merge whose continuation cell lived inside a cell-level SDT was never marked `_vMergeConsumed`; the row encoder would then re-emit it as a real cell and break the merge round-trip. Extract the row-child normalization to a shared helper (`row-cell-children.js`) and route both the row encoder and the vMerge column lookup through it. The inner `<w:tc>` is now reachable from either side; vMerge marking propagates naturally because both sides see the same node reference. Caught by automated review on PR #3539. Adds a unit test covering a vMerge column with an SDT-wrapped continuation cell.
