谁能帮我修改我的代码以便我能够实现以下目标。
1.如何让表格位于第一页的顶部？现在它会跳过第一页并跳转到第二页的中间。
2.图表看起来不太好。有没有办法让它们在第二页的顶部变成 2x2。就像我附上的图片一样（它是 1x3，但我想要 3x2，不确定 2x3 是否看起来更好）。
3.任何其他修改都极受欢迎！

答案1
第一行上方的表格似乎相当棘手。请参阅评论中的链接。其余的，您可以按照我的 MWE 中的方法进行操作。由于subcaption与您的文档类不兼容，我只是将它们放入minipages 中。如果您想要 2x3，只需重新排序空白行和\hfils 即可。

请注意，为了获得更清晰的外观，我不得不删除多少代码。这距离 MWE 还很远。对于以后的问题，请尽量减少。
