import org.pentaho.reporting.engine.classic.core.wizard.DataAttributes;

 * A extension of the classic table-model. If the tablemodel returned by the data-factory implements this interface, the
 * report engine can make use of the extended meta-data provided for each column.
 * <p/>
 * The meta-data given here is presentation level meta-data, so it describes how data from the data-set should be
 * formatted or styled.
 * @author Thomas Morgner
public interface MetaTableModel extends TableModel
   * Returns the meta-attribute as Java-Object. The object type that is expected by the caller is defined in the
   * TableMetaData property set. It is the responsibility of the implementor to map the native meta-data model into a
   * model suitable for reporting.
   * <p/>
   * Be aware that cell-level attributes do not make it into the designtime dataschema, as this dataschema only looks
   * at the structural metadata available and does not contain any data references.
   * @param row    the row of the cell for which the meta-data is queried.
   * @param column the index of the column for which the meta-data is queried.
   * @return the meta-data object.
  public DataAttributes getCellDataAttributes(final int row,
                                              final int column);

   * Checks, whether cell-data attributes are supported by this tablemodel implementation.
   * @return true, if the model supports cell-level attributes, false otherwise.
  public boolean isCellDataAttributesSupported();

   * Returns the column-level attributes for the given column.
   * @param column the column.
   * @return data-attributes, never null.
  public DataAttributes getColumnAttributes(final int column);

   * Returns table-wide attributes. This usually contain hints about the data-source used to query the data as well as
   * hints on the sort-order of the data.
   * @return the table-attributes, never null.
