Linq query c# groupby

My linq query returns the output like this, i.e, multiple arrays, and each array contains 3 elements.

Now i want each array as one column in datatable. How can i store that in datatable or list.

var result = values.Select((l, i) => new { l, i })
.GroupBy(p => p.i % 13)
.Select(x => x.Select(v => v.l).ToList())
