請(qǐng)教，怎么根據(jù) publish_treeData數(shù)據(jù)的expanded和checked屬性去設(shè)置是否默認(rèn)展開和默認(rèn)選中的節(jié)點(diǎn)啊，比如disabled: true就能禁用狀態(tài)

<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: '一級(jí) 2',
                children: [{
                    id: 3,
                    label: '二級(jí) 2-1',
                    children: [{
                        id: 4,
                        label: '三級(jí) 3-1-1'
                        }, {
                        id: 5,
                        label: '三級(jí) 3-1-2',
                        expanded: true,
                        checked: true,
                        disabled: true
                    }]
                }],
