 ## Features
 
 - **DOCX** — paragraphs, inline formatting (bold/italic/underline/color), tables, images, lists, headers/footers, page setup
-- **PPTX** — slides, text boxes, shapes, images, slide masters, speaker notes, gradient backgrounds, shadow/reflection effects
+- **PPTX** — slides, text boxes, shapes, tables (with theme-based table styles), images, slide masters, speaker notes, gradient backgrounds, shadow/reflection effects
 - **XLSX** — sheets, cell formatting, merged cells, column widths, row heights, conditional formatting (DataBar, IconSet)
 - **PDF/A-2b** — archival-compliant output via `--pdf-a`
 - **Embedded font extraction** — fonts embedded in PPTX/DOCX are automatically extracted, deobfuscated, and used during conversion
