主题：excel报表

 请问下，下面代码总是筛选全部数据，怎么修改成按照筛选条件筛选呢？
Dim Book As New XLS.Book(ProjectPath & "Attachments\报价表.xls") '打开模板
Dim fl As String = ProjectPath & "Reports\报价表.xls"

Dim Sheet As XLS.Sheet = Book.Sheets(0)
Dim Filter As String
With e.Form.Controls("DateTimePicker1")
    If .Value IsNot Nothing Then
        If Filter > "" Then
            Filter = Filter & " And "
        End If       
        Filter = Filter & "报价日期 = '" & .Value & "'"   
        'Filter = Filter & "报价日期 = #" & .Value & "#"   '如果是内部表
 End If
End With
With e.Form.Controls("ComboBox1")
    If .Value IsNot Nothing Then
        If Filter > "" Then
            Filter = Filter & " And "
        End If
        Filter = Filter & "旺旺QQ = '" & .Value & "'"
    End If
End With

If filter > "" Then
    Sheet(1,13).Value = "<" & filter & ">"
Else
    Sheet(1,13).Value = "<all>"
End If
Book.Build() '生成报表
Book.Save(fl)
Dim Proc As New Process
Proc.File = fl
Proc.Start()
