I really need your help for a google script project. I have a sheet with 2 tabs. One with parameters and associated coefficients. (columns 1, 2 and 3) --> TAB 1

I have another tab with other parameters (some parameters are in common) and associated coefficients --> TAB 2

I'd like to create a code that imports the coefficients from TAB 2 and places them next to the correct parameters on TAB 1. In other words, I would like to compare them so place them right next to the coefficients already filled in and opposite the correct parameter in TAB 1.

My code may need to start with something like:

var identifiers = []
  var database = []
  Base.getRange('A11:L' + Base.getLastRow()).getValues().forEach(r => {
    let id = r[0].toString()
    if (r[7] != '') {
      ids.push(id)
      dataBase.push([r[7], r[8]])
    }
    if (r[9] != '') {
      ids.push(id)
      dataBase.push([r[9], r[10]])
    }
    if (r[11] != '') {
      ids.push(id)
      dataBase.push([r[11], r[12]])
    }
  })`

I need your help, thank you in advance
