Saving a variable as a variable

So, I am making an API, and what I want to do is have the player input a name as table arguements

function test(name)

But then I want to save what ever he inputted as "name" as the name of a table.
Any help?
(I have no current code)

Should be easy enough

local tNames = {}
function test(name)
  tNames[name] = {}
end

Thanks!
