TableItem[] items = table.getItems();

           for(int i=0;i<items.length;i++)

           {

              final TableEditor editor = new TableEditor(table);

              final Text text = new Text(table,SWT.None);

              text.setText(items[i].getText(0));

              editor.grabHorizontal = true;

              editor.setEditor(text, items[i], 0);

              text.addModifyListener(new ModifyListener(){

 

                  @Override

                  publicvoid modifyText(ModifyEvent e) 

                  {

                     editor.getItem().setText(2,text.getText());

                  }

                  

              });

當你更改items[i].getText( 0 ));和 editor.setEditor(text, items[i], 0);這個兩個語句的“0”這個參數時，會改變可編輯的列。比如兩處的  0  都改成 1，你就可以更改第二列了。
