You can either delete the first row using example above  or use LINQ to manipulate the data in the datatable as so:

Use ImportRow For each Row you can copy:

    Dim Rows = T1.Select
    For N = 1 To Rows.Length - 1
        t2.ImportRow(Rows(N))
    Next

This copy not deleted rows (T1.Select), skiping First row.

Note that you can Filter or Sort using Select.
Note that this method also copy RowState (DataRowVersion.Current and DataRowVersion.Original)

dt2.Rows.RemoveAt(0)
