主题：排序和新增

 已经有10行，我进行排序，再新增5行，这五行要怎么定位？用FindRow定位行吗？

     Dim t As Table = Tables("制单表.正式制单单明细")
    t.AddNew(tb.GetCheckedRows.count)
    Dim i As Integer = t.rows.count - 1
    For Each dr As Row In tb.GetCheckedRows
        Dim r As Row = t.rows(i)
        r("维修编号") = dr("维修编号")
 
        i = i - 1
