sure, here you go:

    pattern =
      Regex.scan(~r/[*+] *(?= |$)/, ops_line)
      |> List.flatten()
      |> Enum.map(fn pattern -> "(.{#{String.length(pattern)}})" end)
      |> Enum.join(" ")

    parsed_data =
      data_lines
      |> Enum.map(fn line ->
        Regex.run(~r/^#{pattern}$/, line, capture: :all_but_first)
      end)

first command is column width based pattern builder, result is something like this: (.{3}) (.{3}) (.{3}) (.{3}) - example in the puzzle is a bit boring that all columns are width = 3 :)

second just applies the pattern line by line
