 - **Table width = sum of columnWidths** - for DXA, ensure they add up exactly
 - **Always add cell margins** - use `margins: { top: 80, bottom: 80, left: 120, right: 120 }` for readable padding
 - **Use `ShadingType.CLEAR`** - never SOLID for table shading
+- **Never use tables as dividers/rules** - cells have minimum height and render as empty boxes (including in headers/footers); use `border: { bottom: { style: BorderStyle.SINGLE, size: 6, color: "2E75B6", space: 1 } }` on a Paragraph instead. For two-column footers, use tab stops (see Tab Stops section), not tables
 - **TOC requires HeadingLevel only** - no custom styles on heading paragraphs
 - **Override built-in styles** - use exact IDs: "Heading1", "Heading2", etc.
 - **Include `outlineLevel`** - required for TOC (0 for H1, 1 for H2, etc.)
