     * The ATK interface implemented for UI components which contain tabular or row/column information.
     * 
     * {@link Atk.Table} should be implemented by components which present
     * elements ordered via rows and columns.  It may also be used to
     * present tree-structured information if the nodes of the trees can
     * be said to contain multiple "columns".  Individual elements of an
     * {@link Atk.Table} are typically referred to as "cells". Those cells should
     * implement the interface {@link Atk.TableCell}, but `Atk` doesn't require
     * them to be direct children of the current {@link Atk.Table}. They can be
     * grand-children, grand-grand-children etc. {@link Atk.Table} provides the
     * API needed to get a individual cell based on the row and column
     * numbers.
     * 
     * Children of {@link Atk.Table} are frequently "lightweight" objects, that
     * is, they may not have backing widgets in the host UI toolkit.  They
     * are therefore often transient.
     * 
     * Since tables are often very complex, {@link Atk.Table} includes provision
     * for offering simplified summary information, as well as row and
     * column headers and captions.  Headers and captions are `AtkObjects`
     * which may implement other interfaces ({@link Atk.Text}, {@link Atk.Image}, etc.) as
     * appropriate.  {@link Atk.Table} summaries may themselves be (simplified)
     * `AtkTables`, etc.
     * 
     * Note for implementors: in the past, {@link Atk.Table} required that all the
     * cells should be direct children of {@link Atk.Table}, and provided some
     * index based methods to request the cells. The practice showed that
     * that forcing made {@link Atk.Table} implementation complex, and hard to
     * expose other kind of children, like rows or captions. Right now,
     * index-based methods are deprecated.
