请教，怎么根据 publish_treeData数据的expanded和checked属性去设置是否默认展开和默认选中的节点啊，比如disabled: true就能禁用状态

<el-tree
    :data="publish_treeData"
    show-checkbox
    node-key="id"
    :default-expanded-keys="defaultExpandedKeys"
    :default-checked-keys="defaultCheckedKeys"
    @setChecked="setCheckedFunc">
</el-tree>

 publish_treeData: [{
                id: 1,
                label: '一级 2',
                children: [{
                    id: 3,
                    label: '二级 2-1',
                    children: [{
                        id: 4,
                        label: '三级 3-1-1'
                        }, {
                        id: 5,
                        label: '三级 3-1-2',
                        expanded: true,
                        checked: true,
                        disabled: true
                    }]
                }],
