Answer / shrikrishna kashid
With the JTable class you can display tables of data,
optionally allowing the user to edit the data. JTable does
not contain or cache data; it is simply a view of your data.

Answer / narmada
The JTable is used to display and edit regular two-dimensional tables of cells.
The JTable has many facilities that make it possible to customize its rendering and editing but provides defaults for these features so that simple tables can be set up easily. For example, to set up a table with 10 rows and 10 columns of numbers:
TableModel dataModel = new AbstractTableModel() {
public int getColumnCount() { return 10; }
public int getRowCount() { return 10;}
public Object getValueAt(int row, int col) { return new Integer(row*col); }
};
JTable table = new JTable(dataModel);
JScrollPane scrollpane = new JScrollPane(table);
