Remove extra border and put all border in last row of generated output

Hello everyone,

I am able to create the output from macro but getting some extra border in column K of sheet overview. How to remove this border.
Along with that, the last row should be bordered with bold font and white background.
After that, one outerborder on all data of table will be there. (that means exact output will be in sheet3).
Is it possible to create a pdf with this dynamic pivot.
your help will be highly appreciated
