问题描述
当模型回复中包含 ```markdown 代码块，且代码块内部含有表格时，界面会将表格错误渲染，导致代码块结构被破坏，无法完整复制原始文本。

复现步骤

打开 https://chat.deepseek.com，开始新对话。
发送以下消息：
"请在单个 Markdown 代码块内输出以下内容，不要做任何额外解释：一个一级标题、一段文字，一个嵌套的 Python 代码块，一个五行五列的表格、一个无序列表，以及一行普通文字。"
查看模型回复。
尝试从代码块开头拖选到结尾并复制。
粘贴到纯文本编辑器。

实际结果
表格被渲染成可视化表格，代码块标记失效，复制后无法得到原始 Markdown。

预期结果
代码块内所有内容以纯文本原样显示，不被渲染。

@JodieFoster233 Thanks for filing your first issue — and with such a clear reproduction.

Workaround (for now):
When a Markdown code block gets partially rendered (e.g., the table turns into a visual table), copy the already rendered parts and ask the model again to output only the missing pieces (e.g., "please output the table inside the code block as plain Markdown"). Repeat until you recover the full block. It’s manual, but it works.

This is not a fix — it’s a way to unblock yourself. We’ve logged the rendering defect and will include it in our next feedback batch to the team.

Thanks again for surfacing this.
