窗口里面的页面标签，切换到其中的某个标签后，按钮和筛选器对表都不起作用了?不切换到这些标签的时候还没有问题。

按钮的语句：

With Tables("绿建国标条款")

.Position = .Position + 1

End With

筛选器的语句：

Dim Filter As String

With e.Form.Controls("tx")

If .Value IsNot Nothing Then

Filter = "条文归属 = '" & .Value & "'"

End If

End With

With e.Form.Controls("qd")

If .Value IsNot Nothing Then

If Filter > "" Then

Filter = Filter & " And "

End If

Filter = Filter & "条文分类 = '" & .Value & "'"

End If

End With

With e.Form.Controls("bj")

If .Value IsNot Nothing Then

If Filter > "" Then

Filter = Filter & " And "

End If

Filter = Filter & "标记 = '" & .Value & "'"

End If

End With

With e.Form.Controls("zy")

If .Value IsNot Nothing Then

If Filter >"" Then

Filter = Filter & " And "

End If

Filter = Filter & "专业分类 like '%" & .Value & "%'"

End If

End With

With e.Form.Controls("ny")

If .Value IsNot Nothing Then

Filter = "难易度 = '" & .Value & "'"

End If

End With

If Filter > "" Then

Tables("绿建国标条款").Filter = Filter
