Overview

Renders an IDML Table. Draws the cell grid via rectangle ops, then renders inline text in each cell via canvas.text_rich. Cells with no text render as empty rectangles.

Two table layouts are supported:

1. **Schema-faithful** (real IDML): `Table` has `cell`
 and `row` sibling collections. Cell `Name` encodes
 column and row as `"col:row"`. Row order determines
 vertical position; cell Name determines horizontal.
2. **Legacy** (synthetic test fixture): `Table` has a
 `table_row` collection, each `TableRow` has a
 `table_cell` collection. Nested structure.

The renderer auto-detects which layout is present.
