tree-structure table 展开后，scrollToIndex定位不准。

[ilostidea]

例如：当数据中有 children 字段时会自动展示为树形表格，但展开父节点后，scrollToIndex定位不准。
const data: RecordType[] = new Array(1000).fill(null).map((_, index) => ({
id: index,
firstName: First_${index.toString(16)},
lastName: Last_${index.toString(16)},
children: [{
id: index + ".1",
firstName: First_${index.toString(16)}. 1,
lastName: Last_${index.toString(16)}. 1,
},{
id: index + ".2",
firstName: First_${index.toString(16)}. 2,
lastName: Last_${index.toString(16)}. 2,
}]
}));
