Applescript: copy between 2 documents in numbers

I have a document in numbers with a lot of information of my calculations, which I get out of an other software. Now, to make my report, I want to make a table with al of my assumptions (of my calculations). I already have written a script to extract all the data I want in my report. But now, I want to pimp my table, so it looks better. (putting tings in bold, use sub- and superscript, column headers, units, color cells and so on.). I had the idea to make a template in which I can then copy al the values, so, that they have the correct formatting.

Can anyone help me how to copy a table between 2 documents in numbers, using AppleScript?

[Another way I can do it, is to do the formatting in numbers with AppleScript. I can color cells, set them in bold… but I don’t know how to use superscript (for example for m²). If someone can tell me how to do that… that would be also very helpfull)

Thank in advance!
