npm install vue3-markdown-it 

注意是vue3-markdown-it 不是 markdown-it

这个是对输出的文字做优化。

import Markdown from "vue3-markdown-it";
<div style="text-indent: 2em; padding: 0 6px; background: #ddd;">{{ dialog.reasoning_content }}</div>
        <!-- <div style="font-weight: bold; text-indent: 2em; margin-top: 10px;" v-if="dialog.flag">{{ dialog.content }}</div>
          -->
        <Markdown :source="dialog.content" style="font-weight: bold; margin-top: 10px;"></Markdown>

如果没有vue3-markdown-it，样式会很难看，而且没法输出表格
