how to change the citation order into columns in table?

In the table, if I insert citations for two columns of data, the order in table is incorrect.

The citation just sort rows by display name, how to change it into columns?

The only fix I can see is to break the table into two adjacent tables (with no space between them, maybe in two word columns or two frames?) so they are next to each other, as the citation order is dictated by the way Word accesses and processes fields in a table, not by EndNote.
