如果表A和表B的结构不同，或者只需填充部分列，就需要定义数据来源列和数据接收列，例如：
Dim Cols1() As String = {"来源列一","来源列二","来源列三"}
Dim Cols2() As String = {"接收列一","接收列二","接收列三"}
For Each dr1 As DataRow In DataTables("表A").Select("[金额] > 100")
Dim dr2 As DataRow = DataTables("表B").AddNew()
For i As Integer = 0 To Cols1.Length -1
dr2(Cols2(i)) = dr1(Cols1(i))
Next
