About right border

1. Hard to say, please Code Inspector from your browser and check why you don't see it.
2. Check Table settings: General - Table Styles - Row(<tr>) & Data(<td>) Style Options - Border Width and Border Color etc.

Where is the right border of the table?

Well, you either do it everywhere, or you don't do it anywhere.

And it turns out that in one addon you have template styles applied, and in the other you do not have to style them with your hands.

There is no unity of settings.

Where does the first row of the table go? https://mega.nz/file/zuhFSIDa#QVQmMguQgOlcNCS9pikahrOsQ3NJFOpyZ3XRotHdlx0

Hi, you can define colors for tables using custom CSS. One for all !

Don't forget that Template =/= Component - those are two different products.

Are you serious?

I could say this same.
