+keys | Object | - | 用来定义 `value / label / disabled / children` 在 `data` 数据中对应的字段别名，示例：`{ value: 'key', label 'name', children: 'list' }`。其中，disabled 待开发。。TS 类型：`TreeKeysType`。[通用类型定义](https://github.com/Tencent/tdesign-vue/blob/develop/src/common.ts) | N
 label | String / Boolean / Slot / Function | true | 自定义节点内容，值为 `false` 不显示，值为 `true` 显示默认 label，值为字符串直接输出该字符串。泛型 `T` 表示树节点 TS 类型。<br/>如果期望只有点击复选框才选中，而点击节点不选中，可以使用 `label` 自定义节点，然后加上点击事件 `e.preventDefault()`，通过调整自定义节点的宽度和高度决定禁止点击选中的范围。TS 类型：`string \| boolean \| TNode<TreeNodeModel<T>>`。[通用类型定义](https://github.com/Tencent/tdesign-vue/blob/develop/src/common.ts) | N
 lazy | Boolean | true | 延迟加载 children 为 true 的节点的子节点数据，即使 expandAll 被设置为 true，也同样延迟加载 | N
 line | Boolean / Slot / Function | false | 连接线。值为 false 不显示连接线；值为 true 显示默认连接线；值类型为 Function 表示自定义连接线。TS 类型：`boolean \| TNode`。[通用类型定义](https://github.com/Tencent/tdesign-vue/blob/develop/src/common.ts) | N
 load | Function | - | 加载子数据的方法，在展开节点时调用（仅当节点 children 为 true 时生效），泛型 `T` 表示树节点 TS 类型。TS 类型：`(node: TreeNodeModel<T>) => Promise<Array<T>>` | N
-maxHeight | String / Number | - | 表格最大高度，超出后会出现滚动条。示例：100, '30%', '300'。值为数字类型，会自动加上单位 px | N
+maxHeight | String / Number | - | 树的最大高度，超出后会出现滚动条。示例：100, '30%', '300'。值为数字类型，会自动加上单位 px | N
 operations | Slot / Function | - | 自定义节点操作项，泛型 `T` 表示树节点 TS 类型。TS 类型：`TNode<TreeNodeModel<T>>`。[通用类型定义](https://github.com/Tencent/tdesign-vue/blob/develop/src/common.ts) | N
 scroll | Object | - | 懒加载和虚拟滚动。为保证组件收益最大化，当数据量小于阈值 `scroll.threshold` 时，无论虚拟滚动的配置是否存在，组件内部都不会开启虚拟滚动，`scroll.threshold` 默认为 `100`。TS 类型：`TScroll`。[通用类型定义](https://github.com/Tencent/tdesign-vue/blob/develop/src/common.ts) | N
 transition | Boolean | true | 节点展开折叠时是否使用过渡动画 | N
