Creation and access
To create a new NotesRichTextTable object, use the AppendTable method in NotesRichTextItem.
To access a NotesRichTextTable object, use the NotesRichTextNavigator methods in conjunction with the type RTELEM_TYPE_TABLE.
To access the cells in a table, use the NotesRichTextNavigator methods in conjunction with the type RTELEM_TYPE_TABLECELL.
The order of cells in a table is by row, then column.
You cannot determine the contents of a cell (text paragraphs, text runs, doclinks, and so on) unless you know the exact structure of the rich text item.
