Hellow everybody!

I have MediaWiki and extension Page Forms. On the extension page https://www.mediawiki.org/wiki/Extension:Page_Forms/Defining_forms#Spreadsheet-style_editing, I saw that it is possible to add a table view for templates as on this page https://discoursedb.org/w/index.php?title=Special:MultiPageEdit&template=Author&form=Author To do this, you need to connect the JsGrid library. I installed the library itself, but I can't figure out how to connect it to MediaWiki and use it. I can't find any documentation on how to use it in MediaWiki. I am far from a programmer myself, but such a task has arisen. Has anyone ever done something like this? Can you tell me how to do it? Thank you very much.
