我正在尝试找到一种方法来正确地将表格放在表格旁边，我发现了这一点，但是改变第一个值textwidth却没有得到想要的结果。我希望这两个物体居中，因为它们是一个独特的物体，但正如您在图片中看到的，它们更靠近右侧。我认为我的错误与环境有关minipage，但不明白如何解决。

答案1
全部删除minipage，将 设置baseline为，并在 之前添加tikzpicture一个。您可以使用 增加图表和表格之间的空间。增加可能会稍微改善表格，在分数和s 之间留出一些额外的空间。\centering\begin{tikzpicture}\hspace{<length>}\arraystretch\hline
（图像中的框架是由于showframe的选项而产生的geometry。）
