				To remove a column to a JTable component, the component must use a table model that supports this operation. A simple implementation of such a table model is DefaultTableModel. 
				DefaultTableModel.removeColumn() removes the visible column, but leaves the column data in the table model. This example provides a routine that removes both the visible column and the column data. 
				
				    DefaultTableModel model = new MyDefaultTableModel();
				    JTable table = new JTable(model);
				    table.setModel(model);
				    
				    // Create 3 columns
				    model.addColumn("Col1");
				    model.addColumn("Col2");
				    model.addColumn("Col3");
				    model.addRow(new Object[]{"v1"});
				    
				    // Remove the first visible column without removing the underlying data
				    table.removeColumn(table.getColumnModel().getColumn(0));
				    
				    // Disable autoCreateColumnsFromModel to prevent
				    // the reappearance of columns that have been removed but
				    // whose data is still in the table model
				    table.setAutoCreateColumnsFromModel(false);
				    
				    // Remove the first visible column and its data
				    removeColumnAndData(table, 0);
				    
				    // Remove the last visible column and its data
				    removeColumnAndData(table, table.getColumnCount()-1);
				    
				    // Removes the specified column from the table and the associated
				    // call data from the table model.
				    public void removeColumnAndData(JTable table, int vColIndex) {
				        MyDefaultTableModel model = (MyDefaultTableModel)table.getModel();
				        TableColumn col = table.getColumnModel().getColumn(vColIndex);
				        int columnModelIndex = col.getModelIndex();
				        Vector data = model.getDataVector();
				        Vector colIds = model.getColumnIdentifiers();
				    
				        // Remove the column from the table
				        table.removeColumn(col);
				    
				        // Remove the column header from the table model
				        colIds.removeElementAt(columnModelIndex);
				    
				        // Remove the column data
				        for (int r=0; r				            Vector row = (Vector)data.get(r);
				            row.removeElementAt(columnModelIndex);
				        }
				        model.setDataVector(data, colIds);
				    
				        // Correct the model indices in the TableColumn objects
				        // by decrementing those indices that follow the deleted column
				        Enumeration enum = table.getColumnModel().getColumns();
				        for (; enum.hasMoreElements(); ) {
				            TableColumn c = (TableColumn)enum.nextElement();
				            if (c.getModelIndex() >= columnModelIndex) {
				                c.setModelIndex(c.getModelIndex()-1);
				            }
				        }
				        model.fireTableStructureChanged();
				    }
				    
				    // This subclass adds a method to retrieve the columnIdentifiers
				    // which is needed to implement the removal of
				    // column data from the table model
				    class MyDefaultTableModel extends DefaultTableModel {
				        public Vector getColumnIdentifiers() {
				            return columnIdentifiers;
				        }
				    }
