提供兩種方式的分類樹格式，表格和下拉框形式的樹形結構
可以自定義表格和下拉框的樣式，自定義以哪一列的參數為格式化數據，自定義層級關系參數，自定義表格列名稱，也可以設置時間的格式化。

調用方式

表格方式：

widget('ext.tree.widgets.TreeWidget',array(
??????? 'dataProvider'? => $dataProvider,?????????? // 傳遞數據
??????? 'pid'?????????? => 'pid',?????????????????? // 設置層級關系id
??????? 'tableClass'??? => 'items table table-striped table-bordered table-condensed',? // 表格樣式
??????? 'formatParam'?? => 'name',????????????????? // 設置格式化字段??? 
??????? 'formatTime'??? => array(?????????????????? // 設置格式化的時間參數
??????????? 'created'
??????? ),?????????????? 
??????? 'tableHead'???? => array(?????????????????? // 設置表格列頭信息
??????????????? '分類ID',
??????????????? '頻道',
??????????????? '中文名',
??????????????? '英文名',
??????????????? '首字母',
??????????????? '排序',
??????????????? '分類級別',
??????????????? '父ID',
??????????????? '創建時間',
??????? ),??? 
??? )); ?>

下拉框方式

widget('ext.tree.widgets.TreeWidget',array(
??????????? 'dataProvider'? => $cate,?????????? // 傳遞數據
??????????? 'pid'?????????? => 'pid',?????????????????? // 設置父ID??????????? 
??????????? 'formatParam'?? => 'name',????????????????? // 設置格式化字段
??????????? 'treeType'????? => false,?????????????????? // 輸出樹格式
??????????? 'selectClass'? => 'class="span11"',???????? // 設置下拉框樣式
???????????? 'defaultSelectValue' => array(???????????? // 設置下拉框的默認值和選項
??????????????????? 0 , '≡ 作為一級欄目 ≡'
???????????? ),
??????? )); ?>
