The example below creates a new DataTable from an array of objects. The raw array is put into a public property called Rows. Also, a Columns array is created that contains information about each column in the data table.
let users =[
let table =newwire.data.DataTable(rows);
const rows = table.Rows;
const columns = table.Columns;
Note, it's a good idea to use let or var scope when declaring arrays of rows to be used with a data table. The array sits inside a data table as a reference and not a copy so using operations on the data table that are designed to change the data or the array will error if the array is declared using a const. However, if the table is being created for read-only purposes, it's safe to use a const.
