public class TableProxy
extends ColumnProxy
implements Table, TableModelListener

A Table Proxy implements an Table by forwarding all the methods to an internal Table.

This class is useful to implements higher level containers out of a standard DefaultTable.

TableProxy(Table table)
Creates a new TableProxy object.

Method Summary

void	addColumn(Column c) Adds a column.
void	addTableModelListener(TableModelListener l)
void	clear() Removes all of the elements from this column. The Column will be empty after this call returns. WARNING: if there is an associated format that maintains a status, such as a CategoricalFormat, it is not cleared so results may not be what you expected. The CategoricalFormat can be cleared explicitely if needed.
Column	getColumn(String name) Returns the column of a specified name.
Column	getColumnAt(int index) Returns the column at a specified index.
Class	getColumnClass(int columnIndex)
int	getColumnCount() Returns the number of columns of the table.
String	getColumnName(int columnIndex)
int	getLastRow() Returns the index of the last row in the table.
int	getRowCount() Returns the number of rows in the table.
Table	getTable() Returns the real table for Proxies and this for a concrete table.
Object	getValueAt(int rowIndex, int columnIndex)
int	indexOf(Column column) Returns the index of a specified column.
int	indexOf(String name) Returns the index of a column of a specified name.
boolean	isCellEditable(int rowIndex, int columnIndex)
boolean	isRowValid(int row) Checks whether a specified row is valid.
boolean	removeColumn(Column c) Removes a column from the table.
void	removeTableModelListener(TableModelListener l)
RowIterator	reverseIterator() Returns an iterator over the columns of this table in reverse order.
void	setColumnAt(int i, Column c) Replaces the column at a specified index.
void	setValueAt(Object aValue, int rowIndex, int columnIndex)
void	tableChanged(TableModelEvent e)
