Bug Report
When exporting with TaggingStrategyType.Build, automatic table detection can include surrounding content in the table and generate rows, cells, and header associations that do not match the document’s logical structure. Headings may become table-cell content instead of remaining separate elements.
The exported PDF may pass automated accessibility validation despite having incorrect semantics for screen readers.

Feature Request
Provide a public API for setting the Scope attribute on explicitly created table-header (TH) structure elements.
Currently, StructureElement.Attributes, StructureElementTableAttributes, and TableScopeAttribute are internal. Applications can create TH elements but cannot directly specify whether headers apply to a row, column, or both.
This prevents PDF/UA-1 compliance when table relationships are not defined through Headers and IDs.
