主题：逻辑列自动复制行问题，请教老师们

一样：

If e.DataCol.Name = "逻辑列名" AndAlso e.DataRow("逻辑列名") = True Then
    Dim nma() As String = {"A1","A2","A3","A4"} 'A表数据来源列
    Dim nmb() As String = {"B1","B2","B3","B4"} 'B表和C表数据接收列
    Dim dr1 As DataRow = DataTables("表B").AddNew
    Dim dr2 As DataRow = DataTables("表C").AddNew
    For i As Integer = 0 To nma.Length - 1
        dr1(nmb(i)) = e.DataRow(nma(i))
        dr2(nmb(i)) = e.DataRow(nma(i))
    Next
End If

如果长度不一致，要分开写才行：

If e.DataCol.Name = "逻辑列名" AndAlso e.DataRow("逻辑列名") = True Then
    Dim nma() As String = {"A1","A2","A3","A4"} 'A表数据来源列
    Dim nmb() As String = {"B1","B2","B3","B4"} 'B表数据接收列
    Dim nmc() As String = {"B1","B2"} 'C表数据接收列
    Dim dr As DataRow = DataTables("表B").AddNew
    Dim cr As DataRow = DataTables("表C").AddNew
    For i As Integer = 0 To nmb.Length - 1
        dr(nmb(i)) = e.DataRow(nma(i))
    Next
    For i As Integer = 0 To nmc.Length - 1
        cr(nmc(i)) = e.DataRow(nma(i))
    Next
End If
