主题：有点甜老师，您再帮我看看，着急

 哦，你改一下代码

If e.DataCol.Name.StartsWith("工序") Then
    Dim filter As String = "产品名称 = '" & e.DataRow("产品名称") & "'"
    Dim fdr As DataRow = DataTables("产品信息").Find(filter)
    If fdr IsNot Nothing Then
        Dim fdr2 As DataRow  = DataTables("工时统计").Find(filter & " and 单号 = '" & e.DataRow("单号") & "'")
        If fdr2 Is Nothing Then
            fdr2 = DataTables("工时统计").AddNew
            fdr2("产品名称") = e.DataRow("产品名称")
            fdr2("日期") = e.DataRow("日期")
            fdr2("单号") = e.DataRow("单号")
            fdr2("数量") = e.DataRow("数量")
        Else
            For Each dc As DataCol In DataTables("工时统计").DataCols
                If dc.Name <> "日期" AndAlso dc.name <> "产品名称" AndAlso dc.name <> "单号" AndAlso dc.Name <> "数量" Then
                    fdr2(dc.name) = Nothing
                End If
            Next
        End If
       
        For Each dc As DataCol In DataTables("工时统计").DataCols
            If dc.Name.StartsWith("工序") Then
                fdr2(dc.Name) = Nothing
            End If
        Next
        For Each dc As DataCol In e.DataTable.DataCols
            If dc.Name.StartsWith("工序") AndAlso e.DataRow(dc.name) > "" Then
                Dim names() As String = e.DataRow(dc.name).split(",")
                For Each name As String In names
                    Dim sum As Double = e.DataTable.Compute("sum(数量)", filter & " and 单号 = '" & e.DataRow("单号") & "' and " & dc.Name & " like '*" & name & "*'")
                    sum = sum * fdr(dc.Name)
                    If DataTables("工时统计").DataCols.Contains(name) Then
                        fdr2(name) += sum
                    End If
                Next
            End If
        Next
    Else
        msgbox("没有找到【产品信息】对应的数据!")
