我不确定我是否理解了您的要求，但在我看来，您想要一个占据整列宽度的表格。如果是这种情况，您应该考虑使用将tabular*宽度设置为 的环境\columnwidth。哦，不要对同一个对象同时使用 a\caption和 a指令——这是符号滥用，甚至更糟。\caption*figure

附录解决 OP 的后续评论：使表格材料跨度两个都列，您需要在上面显示的代码中更改答案的所有内容是 (a) 将 的两个实例替换{table}为{table*}并替换\columnwidth为\textwidth。但请注意，LaTeX 只会将 table* 和 figure* 环境放在顶部页面。由于现在空间绰绰有余，footnotesize因此您可能应该删除这些指令。
第二附录：对环境内容的进一步分析table表明：(a) 没有必要切换到\footnotesize；(b) 从使数字信息更具可读性的角度来看，将四个数据列中的数字与其（隐式）小数标记对齐会很有用。这可以通过加载包siunitx并使用S列类型来实现。
另外，由于你正在使用IEEEtran文档类，我会不是加载caption包，因为这样做会相当果断地修改标题的外观。我认为您使用这个包IEEEtran是有充分理由的；因此您应该非常小心地更改表格和图形标题的布局和外观。

如果您坚持将表格跨越两列，尽管其自然宽度小于一列宽度，那么您应该使用
\begin{table*}
...
\end{table*}
（关于这一点，你的问题与这里的许多问题重复...）。这些表格只能出现在（下一页）的顶部。要强制它位于当前页面的底部，你需要加载包stfloats：

这使：
上面的表格中，列格式使用了siunitx列类型S。在我看来，结果非常非常丑陋……好吧，也许你的真实表格需要这么宽，谁知道呢 :)
