当我在使用 的环境中间使用浮点数时adjustwidth，标题会占用整个空间，而不是仅占用调整宽度允许的空间。问题是我想在使用 获得的边距中绘制线条adjustwidth，并且线条与内容重叠：
有没有办法确保我的字幕能够正确显示（如果您有适用于浮点数的更好的解决方案，我可以摆脱 adjustwidth ）？

对于标题，我发现了一个有趣的技巧：\captionsetup。我不确定这是否是最好的解决方案……但确实有效。但不幸的是，它并不适用于所有浮点数。例如，它不适用于使用环境定义的浮点数float。
如果您有更好的解决方案（可能适用于更多类型的浮点数），请告诉我。另外，如果您知道如何将图像居中，我会很感兴趣。

通过添加，\advance\columnwidth-2cm我还设法使用该库更改插入的浮点数的大小float...不幸的是，它仍然不完美，因为浮点数被向左刷新，所以重叠是相同的，并且图片现在甚至更不居中^^

我尝试应用 John 的建议，在浮动元素内插入 adjustwidth。对于图片，我成功了一点（标题仍然表现不正常，要么太大，要么\captionsetup{width=1\linewidth}太小），但对于其他浮动元素，我却失败了：

感谢 David 在 minipages 上的评论，我尝试在图形中创建一个……事实上，它基本上解决了图片的问题（现在我需要自动应用它），如果需要，它实际上可以在新页面上浮动。我仍然需要找到一种方法将所有图形环境修补到我的调整宽度中，但它正在实现。但是，我不确定如何将它应用于其他类型的浮动，如果我在规则环境中这样做，补丁不会应用于标题。
