Answer 1

 DataTable table = new DataTable("table");


DataColumn dc= table.Columns.Add("id", typeof(int));
        dc.AutoIncrement=true;
        dc.AutoIncrementSeed = 1;
        dc.AutoIncrementStep = 1;

// Add the new column name in DataTable

table.Columns.Add("name",typeof(string));

    table.Rows.Add(null, "A");
    table.Rows.Add(null, "B");
    table.Rows.Add(null, "C");
