![双列文档内的聊天气泡](https://linux22.com/image/477856/%E5%8F%8C%E5%88%97%E6%96%87%E6%A1%A3%E5%86%85%E7%9A%84%E8%81%8A%E5%A4%A9%E6%B0%94%E6%B3%A1.png)
我正在尝试制作一个包含聊天记录的文档,发现了一个示例代码在这里除了 documentclass 中的 twocolumn 选项之外。
但是聊天气泡不会保留在栏内。有人知道如何纠正吗?
我想要两列页面的聊天记录。

您需要更改\bubble
命令中的设置。tcolorbox
提供了一个选项,将(的底层命令)tcbox width=auto limited
的宽度设置为自动,\tcbox
\bubble
IE它遵循内容的宽度,但有最大值限制。要设置最大值,您可以使用width=\columnwidth
选项。因此,更改气泡的定义就足够了:
\newcommand{\bubble}[4]{%
\tcbox[
on line,
arc=4.5mm,
colback=#1,
colframe=#1,
tcbox width=auto limited, % <-- added
width=\columnwidth, % <-- added
#2,
]{\color{#3}#4}%
}
输出:
