How to generate the bottom rule for a specific column which is coming in the last row of the table?

I need to generate the bottom rule for a specific column (for example, only for 2nd column) which is the last row of the table. I tried "<?xpp hrule;1?>" and other macros but unable to generate it.

As this is the last row of the table, so none of the macro is generating the bottom rule. If I tried to use "<?xpp setbrul;btmbox;0.5q?>" but that is generating the full bottom rule. 

I am able to generate the bottom rule for a specific column but for that I need to add dummy row at the end of the table which I do not want to add.

I just want to know, is there any other way to generate the bottom rule for a specific column without adding dummy row.

Please advise.

Thanks and Regards,
