比如

(iif(库存_28=0 and 销售_28<>0, 1, 0) + iif(库存_29=0 and 销售_29<>0, 1, 0)) / (iif(销售_28>0, 1, 0) + iif(销售_29>0, 1, 0))

        dic_xl.add(v, c2.name)
    End If
    If c2.Caption.Contains("可用库存_") And c2.Caption.Contains("店仓名称") = False Then
        Dim v  = c2.Caption.Replace("可用库存_","")
        dic_kc.add(v, c2.name)
    End If
Next

For Each r2 As Row In Forms("AA").Controls("table2").Table.Rows
    Dim count1 As Integer = 0

            End If
        End If
    Next
