第二行的列标题

第二行的列标题

我正在构建一个结果表，其中我想让列标题由一行（第一行和最后两行）组成，并与由两行组成的第二行标题对齐。

我知道我没有表达清楚所以我将举一个我想要获得的例子：

在此处输入图片描述

我希望“Outcome”、“Bandiwdth”和“N”位于线的正上方，因为它们与多行列标题的第二行对齐。

我的代码如下：

我强烈建议您不要使用\adjustbox来使表格材料“适合”文本块：这样做很可能会在表格中生成非常小且几乎难以辨认的字符。换句话说：不要使用，\adjustbox除非您想向读者表明您并不真正关心他们是否会尝试仔细阅读表格的内容。

相反，我建议你学习如何利用环境tabularx。在下面的代码中，我将tabularx环境与包的功能相结合dcolumn，以便数字数据在各自的小数点标记上对齐。并且，使用宏的线条绘制宏booktabs来生成间距适当的水平线。

就我个人而言，我不会将“结果”、“带宽”和“N”这几个字向下移动一行。但是，如果您觉得这样做确实有必要，只需\renewcommand{\tabularxcolumn}[1]{b{#1}}在加载tabularx包后插入指令即可。

以下屏幕截图显示了包含建议修改的表格，后面是用于\adjustbox将材料塞入文本块宽度的原始表格代码。我希望你会同意上面的表格更具可读性。:-)
