how to create insert command into access db

I now have a datatable that matches my access db fields and am able to fill the datatable from arrays in my c#. It is 200 X 242.

Now that I have the datatable I want to insert the rows of data, either one by one or batch into access. I attempted the OleCommandBuilder but do not have a primary key in the table. So I'm doing manually I suppose.

Can someone please indicate how I can Insert into my Access table?

Thank you

DataRow row;
            int ln = dtAr.Length;
            //fill rows
                for (int i = 0; i < sims; i++)
                    row = prtab.NewRow();
                    for (int j = 0; j < ln + 2; j++)
                        if (j == 0)
                            row["tStep"] = 1;
                        else if (j == 1)
                            row["SimNum"] = i;
                            row[CrvID[j - 2].ToString() + dtAr[j - 2].ToString()] = crNs[i, j - 2];

how about using SQL to append a record?

INSERT INTO tablename (fieldname1, fieldname2, ...)
SELECT value1, value2, ...

Every table should have a primary key even if it is an autonumber.
