Convert a CSV file to a table with specific keys in Lua

I am learning Lua to create scripts for a flight simulator.

I have a CSV file that looks like this:

Poti city, Poti,red,-295731.42857144,617222.85714285  
Lanchhuti city, Poti,red,-299217.14285715,647851.42857142  
Ozurgeti city, Poti,red,-317217.14285715,648422.85714285  
Samtredia city, Poti,red,-287502.85714287,672022.85714285  
Abasha city, Poti,red,-284245.71428573,661108.57142857

Each row contains 5 fields ( city, region, coalition, coordinate-xand coordinate-yin simulators coordinate system).

I need to read this file as a lua table, which should look like this:

citylist = {
           [1]
           {
              ["city"] = "Poti city",
              ["region"] = "Poti",
              ["coalition"] = "red",
              ["coordinate-x"] = -295731.42857144,
              ["coordinate-y"] = 617222.85714285,
           },
           [2]
           { ....... etcetc

}

I also need to do this for some different csv files, and I tried to look at some of the CSV functions from luawiki, but I honestly don't understand much. Can you write some sample code that should work for parsing a CSV file?

PS: a symbol is never present in csv files ' " '.
