Bug ID: 171503
Summary: FILEOPEN: DrawingML table cells ignore phClr
(placeholder color) from theme styles
Product: LibreOffice
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: filters and storage
Assignee: [email protected]
Reporter: [email protected]
When a .docx or .pptx file contains DrawingML tables with theme-based fill
colors using placeholder color references (phClr), LibreOffice renders the
table cells with incorrect colors.
The phClr mechanism (ISO/IEC 29500, ยง20.1.4.1.24) allows table styles to
reference a placeholder color that gets resolved from the table's style
reference at render time. In LibreOffice's import code
(oox/source/drawingml/table/tablecell.cxx), the nPhClr value is correctly
computed from the table's background fill style reference (line ~564), but is
not passed to FillProperties::pushToPropMap(). This causes the theme color to
remain unresolved.
Steps to reproduce:
1. In Microsoft Office, create a document with a table using a theme-based
table style (e.g., any of the built-in colored table styles)
2. Save as .docx
3. Open in LibreOffice Writer
Expected: Table cell backgrounds match the colors shown in Microsoft Office
Actual: Table cell backgrounds render with incorrect/missing colors
Fix: Pass the already-computed nPhClr as the 4th argument to pushToPropMap().
