class Table(interface):
        """
        An interface used by containers whose contained data is arranged
        in a "tabular" (i.e. row-column) fashion. Tables may resemble
        a two-dimensional grid, as in a spreadsheet, or may feature objects
        which span multiple rows and/or columns, but whose bounds are
        aligned on a row/column matrix. Thus, the Table interface may
        be used to represent "spreadsheets" as well as "frames".
        Objects within tables are children of the Table instance, and
        they may be referenced either via a child index or via a row/column
        pair. Their role may be ROLE_TABLE_CELL, but table 'cells' may
        have other roles as well. These 'cells' may implement other interfaces,
        such as Text, Action, Image, and Component, and should do so
        as appropriate to their onscreen representation and/or behavior.
