Dim Cols3() As String = {"编号", "型号", "规格", "数量", "日期"}'

Dim Cols4() As String = {"编号", "型号", "规格", "数量", "日期"}'

For Each dr3 As DataRow In DataTables("表A").Select("[选中] = true ")'

Dim dr4 As Row = Tables("窗口1_表B").AddNew() '

For r As Integer = 0 To Cols3.Length - 1

dr4(Cols4(r)) = dr3(Cols3(r))

红字代码，报错Row不是DataRow，改为下面代码，也不行

For Each dr3 As Row In DataTables("表A").Select("[选中] = true ")'

窗口1_表B是副表，是 Dim dr4 As Row = Tables("窗口1_表B").AddNew() ，只能正表，不能用副表？
