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());                  }                                });

当你更改items[i].getText( 0 ));和 editor.setEditor(text, items[i], 0);这个两个语句的“0”这个参数时，会改变可编辑的列。比如两处的  0  都改成 1，你就可以更改第二列了。
