ant-desgin-vue——tree自定义节点不可选用的置灰或禁用

效果：

vue:

<template>
    <div class="tree">
        <a-tree showIcon v-if="treeData.length" checkable :treeData="treeData" v-model="checkedId"
                :defaultExpandedKeys="parentId"
                @select="this.onSelect" :replaceFields="replaceFields" checkStrictly
                @check="this.onCheck">
        </a-tree>
    </div>
</template>
