RTF Live Preview

Preview RTF files directly in VS Code or Positron with full formatting, tables, and embedded images.

Tables with borders, column widths, cell backgrounds, and alignment
Horizontal cell merging (colspan) with multi-level header alignment via edge-based column grid
Merged-cell footnote deduplication (SAS-style repeated footnote text suppressed)
Default light cell borders on all tables for consistent readability
Cell padding support
Text indentation (left indent, first-line/hanging indent)
Per-border styling (different widths, colors, and styles per side)
Embedded PNG/JPEG images displayed inline
Font styling (bold, italic, underline, superscript)
Page break indicators
Auto-reloads on file change
Optimized for SAS-generated RTF output
