不是很明白你想要做什么 ……
onChangeOpenKeys
这个回调函数只会在用户通过鼠标点击 展开或收拢某一行的时候被调用。
如果想要主动控制 某个节点的展开状态,直接更新 openKeys 即可;如果想要 控制节点是否展示 展开/收拢箭头,可以提供自定义的 options.isLeafNode 方法。

我想不通过鼠标点击展开或收来控制是否展示。比如我想通过某一个按钮,去控制展开和收拢

@LitterPig 这种情况下,因为 节点的展开/收拢状态是受控的,在按钮的点击回调中 更新一下 openKeys 就好了
function Component() {
const [openKeys, onChangeOpenKeys] = useState([]);
const renderData = applyTransforms(
inputDataSourceAndColumns,
commonTransforms.treeMode({ primaryKey: "id", openKeys, onChangeOpenKeys })
);
return (
<div>
<button
onClick={() => {
onChangeOpenKeys(openKeys.concat(["root"]));
}}
>
展开根节点
</button>
<BaseTable {...renderData} />
</div>
);
}

是的,我现在可以了。感谢提醒~
