Description
Feature Request Description
UI5 Web Components currently does not provide a TreeTable component for displaying hierarchical data in a table format. Such a component would be useful for scenarios where rows have parent-child relationships and users need to expand or collapse different hierarchy levels.
A similar capability is available through the AnalyticalTable component in UI5 Web Components for React.
Proposed Solution
Introduce a TreeTable component in UI5 Web Components that combines standard table functionality with hierarchical row support.
The component should support:
- Expandable and collapsible rows
- Multiple hierarchy levels
- Lazy loading of child rows for larger datasets

Research direction
Start by reviewing the existing UI5 Web Components table capabilities and the linked AnalyticalTable tree-table example. Define the component's scope around expandable rows, multiple hierarchy levels, and lazy loading, then identify the relevant implementation and test entry points. Done means a documented TreeTable component supports all three requested behaviors.
