问题：
我想要生成一个类似（表格＃2）的表格，该表格对于一个父列有两个子列，但我还希望此表格遵守页边距且不会从其余表格中突出来。 （我页面上的其他表格与表格＃1类似，不需要子标题。）这种不遵守页边距的情况发生在较短和较长的表格中。
我从表 #1 中得到了部分信息。有人可以提供一些专业知识或指导吗？

Obeys margin rules but doesn't quite give me the functionality of the multicolumn to span multiple columns..
I noticed this table also wraps it's column headers..

Does not obey Margin rules but gives me the functionality for multiple column spanning
I noticed this table does not wrap it's headers, and forces the table to expand their length.

This uses multicolumn headers and regular body. As you can see the multicolumn doesn't quite match up to the cell.
