只需添加一列配置和编辑为单个列，这里是如何，我认为它会在你的代码工作：

var treePanel = Ext.create('Ext.tree.Panel', { 
    id: 'tree-panel', 
    title: 'Taxonomy', 
    region:'west', 
    collapsible: true, 
    split: true, 
    //multiSelect: true,        
    height:'100%',  
    width: '20%', 
    minWidth: 100, 
    rootVisible: false, 
    autoScroll: true, 
    store: store, 
    viewConfig: { 
    allowCopy: true, 


    plugins: { 
     ptype: 'treeviewdragdrop', 
     appendOnly: true, 
     ddGroup: 'selDD' 
    }, 
    columns: [ 
     { 
      xtype:  "treecolumn", 
      dataIndex: "text", 
      flex:  1, 
      editor:{ 
       xtype:  "textfield" 
      } 
     } 
    ] 
}
