TextEditor lacked a mechanism to showcase or test CPMarkdownParser's
table rendering capabilities within a live document context.
* Tests/Manual/TextEditor/TableExample.j:
- Add a Markdown sample containing a heading, a formatted table with a header row and styled cells, and accompanying text, converted to an attributed string via CPMarkdownParser.
* Tests/Manual/TextEditor/DocumentWindowController.j:
- Implement insertTableExample: action to insert the table sample at the current selection.
* Tests/Manual/TextEditor/Resources/MainMenu.xib, MainMenu.cib:
- Add Edit > Insert Table Example menu item.
* Tests/Manual/TextEditor/WORKLIST.md:
- Record table rendering as tested; log interactive validation and known table limitations as open items.
TextEditor now provides a live demonstration and testing baseline for rich text table layouts.
