1.使用Table，并使用TableEditor将其变为可编辑时，TableEditor的grabVertical和grabHorizontal要设置为true，否则Text控件会不显示，在对应的格子里没有光标显示。

table = new Table(composite, SWT.FULL_SELECTION );		table.setBounds(0, 70, 249, 357);		table.setHeaderVisible(true);		table.setLinesVisible(true);				editor = new TableEditor(table);		editor.grabHorizontal = true;		editor.grabVertical = true;		TableColumn tblclmnNewColumn = new TableColumn(table, SWT.NONE);		tblclmnNewColumn.setWidth(123);		tblclmnNewColumn.setText("Field");				TableColumn tblclmnNewColumn_1 = new TableColumn(table, SWT.NONE);		tblclmnNewColumn_1.setWidth(122);		tblclmnNewColumn_1.setText("Value");				table.addSelectionListener(new SelectionAdapter() {		      public void widgetSelected(SelectionEvent e) {		        // Clean up any previous editor control		        Control oldEditor = editor.getEditor();		        		        if (oldEditor != null)		          oldEditor.dispose();		        // Identify the selected row		        final TableItem item = (TableItem) e.item;		        if (item == null){		        	return;		        }		        		        // The control that will be the editor must be a child of the Table		        final Text newEditor = new Text(table, SWT.NONE);		        newEditor.setText(item.getText(1));		        		        newEditor.selectAll();		        newEditor.setFocus();		        newEditor.addModifyListener(new ModifyListener() {		          public void modifyText(ModifyEvent me) {		            Text text = (Text) editor.getEditor();		            item.setText(1, text.getText());		          }		        });		        editor.setEditor(newEditor, item, 1);		      }		    });
