我正在使用 Overleaf 并使用 IEEEtran 模板撰写论文。我想将一个图形显示在整个页面宽度上并位于页面的中心。但是双列模板不允许我这样做。我的图形代码如下。我根据模板的一侧限制了图像的大小，所以请忽略这一点。我尝试了这figure两种figure*方法，但由于 ieeetran 模板，我的图形只显示在页面的一半。下面给出了测试代码示例。

您可以使用环境 strip（包cuted）将宽材料插入到双列文档中的所需位置。
显然它不支持浮点数，所以您必须使用\captionof{figure}{<text>}插入标题（包caption）。

更新后续问题：长图不适合整个页面。
表格不会跨页。将图表放在新页面的开头，或将表格一分为二，如下例所示。
