Is it possible to access a table without it being in the game?

Ok so I have personally never done this but I believe this is how it works. So you should run the Require function. The way it works is you make a Module script. Then you by calling that you can access a module script. you can do it with:

require(game.workspace.ModuleScript)

-- or

require("Asset Id") -- I am going to talk more about this near the end. This is the one you want.

There is a second function called return. This will send information back to your script. For example a table. So in the Module script you would type:

return { Value = 0 }

So there is an example of what a table would be like. Now in your script you would do:

local module = require(game.workspace.ModuleScript)
print(module.Value)
module.Value = module.Value + 1

That will print 1. If you put it in a for loop it will print 1 then 2 then 3 then 4, etc. Now for the final thing you want. For no one else to be able to access your module script. So make your module script then select it and publish the script making it a Free Model(It doesn't actually have to be for sale). Then you want to copy your asset ID and like it said way at the beginning you do:

require("The asset ID you copied")

--For example, lets say our module script is the example script above with the table and our id is 78623594, we would do

local module = require(78623594)
print(module.Value)
module.Value = module.Value + 1

There! So now that our module script is a model online you can delete it from your workspace! :D. This is my first answer that I have really worked hard on so thanks for reading! :D If you have any questions please comment below and let me know if this helped. :D
