/** Implement this interface to give access to a two-dimensional table.

   <p>The <type>XAccessibleTable</type> interface is used to represent
   two-dimensional tables.  This interface combines the two interfaces
   <code>javax.accessibility.AccessibleTable</code> and
   <code>javax.accessibility.AccessibleExtendedTable</code> of the Java Accessibility API
   (version 1.4).</p>

   <p>All <type>XAccessible</type> objects that represent cells or
   cell-clusters of a table have to be at the same time children of the
   table.  This is necessary to be able to convert row and column indices
   into child indices and vice versa with the methods
   <member>XAccessibleTable::getAccessibleIndex</member>,
   <member>XAccessibleTable::getAccessibleRow</member>, and
   <member>XAccessibleTable::getAccessibleColumn</member>.</p>

   <p>The range of valid coordinates for this interface are implementation
   dependent.  However, that range includes at least the intervals from the
   from the first row or column with the index 0 up to the last (but not
   including) used row or column as returned by
   <member>XAccessibleTable::getAccessibleRowCount</member> and
   <member>XAccessibleTable::getAccessibleColumnCount</member>.  In case of
   the Calc the current range of valid indices for retrieving data include
   the maximal table size--256 columns and 32000 rows--minus one.</p>
