以双列样式嵌入两个并排的图形。（不跨越整个页面，只占第二列）

我有一个典型的 2 列日记模板。我想在第二列插入两个并排的图表。我该怎么做？

我现在的代码是这样的，但是图片从来没有出现过。[图片路径没问题。不是那个问题]

我编辑了我的文件，希望您能直接重现我的问题。要重现，请figure在当前目录下创建一个目录，并将两个图像文件放在fig_1a.png那里fig_1b.png。谢谢！！1

我收到了这个警告。

Package multicol Warning: Floats and marginpars not allowed inside `multicols' 
environment!.

这似乎表明这里不支持浮点数。

答案1

由于multicols不允许浮动环境（这解释了为什么你看不到任何图形），此提案定义了一个名为 的新环境。如你所见，浮动属性被抑制，它会锚定在你想要的位置。此环境也已在包中的命令figurehere上进行了测试。删除中的选项以显示正确的图像subcaptionboxsubcaption[demo]graphicx
