最加数据后不排序，默认是在最后一行的，比如我这样

If e.Col.name = "查看"  Then
    Dim r As Row = Tables("待办事项").Current
    Dim dd As String = r("ID")
    Dim nm As String = r("表名")
    Dim ck As String = r("页签名")
    If DataTables.Contains(nm) = False
        DataTables.Load(nm)
    End If
    Functions.Execute("增加页签",ck,ck)
    DataTables(nm).Save()  \'接下来要根据主键查找,必须先保存,因为只有保存后新增行的主键才是有效值.
    Dim dr As DataRow = DataTables(nm).Find("[ID] = \'" & dd & "\'")
    If dr Is Nothing Then
        DataTables(nm).AppendLoad("[ID] = \'" & dd & "\'")
        dr =  DataTables(nm).Find("[ID] = \'" & dd & "\'")
    Else
        dr.Load()
    End If
    If dr IsNot Nothing Then
        Dim wz As Integer = Tables(nm).FindRow("[ID] = \'" & dd & "\'")
        If wz < 0 Then  \'如果因为筛选导致此合同签订类不可见
            Tables(nm).Filter = ""
            wz =Tables(nm).FindRow(dr)
        End If
        If wz >= 0 Then
            Tables(nm).Position = wz
            Tables(nm).TopVisibleRow = wz   \'定位行后设置为第一个可见行位置,http://www.foxtable.com/webhelp/scr/2358.htm
        End  If
    End  If
End  If
