fix: emptyNode should not shaked when horizontal scroll

[linxianxi]

fix ant-design/ant-design#49279

虽然不会有位置上的变动，但是这样会展示一下白屏再展示 Empty，体验会好一些。

问题的本质是因为第一次 render 时无法获取到 componentWidth 并展示。componentWidth 是 ResizeObserver 监听后还通过 getContainerWidth 然后 setComponentWidth 上去的。这个 pr 还无法完美解决

Table 的一些时序可以合并掉。不过要重构就比较麻烦。现在如果是白屏的话，ssr 体验就比较糟糕了（我印象里header就是白的，就不太好）。

这样闪一下体验更糟吧

Walkthrough

本次更改在 ExpandedRow 组件中，为根元素添加了条件性的 visibility 样式。当行为空、允许横向滚动且组件宽度为假值时，将 visibility 设为 hidden，以解决空状态初始渲染时的显示问题。

空行闪现一瞬间，
代码轻抚隐形帘。
横滚之下藏玄机，
居中展现不再偏。
小兔欢跳来贺变！

Tip

⚡️ Faster reviews with caching

• CodeRabbit now supports caching for code and dependencies, helping speed up reviews. This means quicker feedback, reduced wait times, and a smoother review experience overall. Cached data is encrypted and stored securely. This feature will be automatically enabled for all accounts on May 16th. To opt out, configure Review - Disable Cache at either the organization or repository level. If you prefer to disable all data retention across your organization, simply turn off the Data Retention setting under your Organization Settings.

Enjoy the performance boost—your workflow just got faster.

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Explain this complex logic.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai explain this code block.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and explain its main purpose.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Need help? Create a ticket on our support page for assistance with any issues or questions.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

64-64: 细化注释以增加可读性和上下文
当前注释仅提供了 Issue 链接，建议补充描述性文字，说明为何在此处需要隐藏元素，以便在离线阅读或后续维护时能快速了解本行变更的意图。

---

65-65: 验证 SSR 场景下的表现及优化样式定义
新增的 visibility 控制依赖于 isEmpty && horizonScroll && !componentWidth，请确认在服务端渲染（SSR）环境中 horizonScroll 和 componentWidth 的默认值，避免出现意外的内容隐藏或白屏闪烁。此外，为了与 React 对 style 属性的惯例保持一致，建议将 null 替换为 undefined，从而保证在不需要时该属性不会被注入到最终的 DOM。
