How to use

Provided Dinosaur is defined as:

public class Dinosaur
{
    public string Name { get; }

    public double Weight { get; }

    public string Diet { get; }

    public int ExtinctionMya { get; }

    public Dinosaur(string name, double weight, string diet, int extinctionMya)
    {
        Name = name;
        Weight = weight;
        Diet = diet;
        ExtinctionMya = extinctionMya;
    }
}

You can call the code like this:

using Microsoft.ML;
using TextTabulator;
using TextTabulator.Adapters.MLDotNet;

var list = new List<Dinosaur>
{
    new ("Tyrannosaurus Rex", 6.7, "Carnivore", 66),
    new ("Triceratops", 8, "Herbivore", 66),
    new ("Apatosaurus", 33 ,"Herbivore", 147),
    new ("Archaeopteryx", 0.001, "Omnivore", 147),
    new ("Anklyosaurus", 4.8, "Herbivore", 66),
    new ("Stegosaurus", 3.8, "Herbivore", 147),
    new ("Hadrosaurus", 3, "Herbivore", 66)
};

var mlContext = new MLContext();
var data = mlContext.Data.LoadFromEnumerable(list);

var adapter = new DataViewTabulatorAdapter(data);

var tabulator = new Tabulator();
var table = tabulator.Tabulate(adapter);

Console.WriteLine(table);

This will produce the output:
