How to create a template or variables in google doc that pull data from tables?

Question

Google

The essence of the task: how to make a template in Google Dock that pulls data from a table and fills the header with this data.
Example: we have a folder k on google drive, to which several people have access. One person fills in a simple table with data, the other opens a new document and selects the number of, say, the desired row from the table, and the data is pulled into the header. How can this be done as simply as possible? Thank you.

Only the VLOOKUP and IMPORTRANGE functions come to mind.
