将 dcolumn 中定义的列类型与 tabularx 结合起来，第 2 部分

这是对我问的另一个问题。我正在尝试将dcolumn包与tabularx（或tabular*就此而言）结合起来，以便表格跨越我指定的宽度，列间距均匀，单元格按小数点对齐。

这是我现在所拥有的在此处输入图片描述

另一个问题的答案中建议的技巧是在环境中使用“D”列tabularx，然后\multicolumn在表格前几行中的 s 内使用“X”列。这在该问题给出的示例中效果很好。但现在我有一个很长的文本\multicolumn。“X”列似乎“忽略”了要跨越的列数\multicolumn。将“X”更改为“c”可防止单元格中断，如下所示：在此处输入图片描述

我认为一个解决方案是使用“p”列。但在我看来，指定列宽违背了目的，除非有自动执行的方法——我试图获得一些灵感从这个问题的答案这里但没走多远。

关于如何让文本跨越两列，您有什么想法吗？

编辑：这是我认为理想的基本想法。通过声明\tracingtabularx，tabularx 将打印最佳列宽。所以我第一次使用“X”列，看到 tabularx 在我的日志文件中回显的内容，将其乘以 2，然后将 X 列更改为具有计算宽度的“p”列。当然，手动执行此操作毫无意义。我想要的是让 tabularx 为我完成此操作。

以下是生成上述表格的代码：

您可以通过对 提供一点帮助来实现tabularx；因为您想要跨越两个等宽的列，所以您告诉 LaTeX 自然宽度是保留宽度的两倍，加上 的两倍\tabcolsep。

将长线放在 \parbox 中对我来说有效

                  & \mc{1}{X}{}       & \mc{2}{c}{\parbox{.5\columnwidth}{A very long text that should be wrapped. 'p' would defeat the purpose.}}  \\ \cmidrule{3-4}
