老师好！

为统计表的5个临时列循环行、赋值，非常慢，是不是代码写的有问题？

For Each r As Row In Tables("批量选股_table10").Rows    ’窗口表循环行
    If r("日期") <= Date.Today Then
        Dim dr1 As DataRow
        dr1 = DataTables("股票日线").SQLFind("代码 = \'999999\' and 日期 = \'" & r("日期") & "\'")
        If dr1 IsNot Nothing
        r("上证指数") = dr1("涨跌幅")
        End If
       
        Dim dr2 As DataRow
        dr2 = DataTables("股票日线").SQLFind("代码 = \'399001\' and 日期 = \'" & r("日期") & "\'")
        If dr2 IsNot Nothing
            r("深圳成指") = dr2("涨跌幅")
        End If
       
        Dim dr3 As DataRow
        dr3 = DataTables("股票日线").SQLFind("代码 = \'399005\' and 日期 = \'" & r("日期") & "\'")
        If dr3 IsNot Nothing
