上传实例，说明问题，这段代码本来，就是不是筛选的啊。

'此函数用于更新主窗口左侧的Treeview控件
Dim TvwCtl As WinForm.TreeView = Args(0)   '要更新的Treeview控件
Dim TblName As String = Args(1)            '数据来源表
Dim Columns As String = Args(2)            '要构建Treeview的字段
If Tables(TblName).Rows.Count = 0 Then Return Nothing
TvwCtl.Form.StopRedraw
TvwCtl.BuildTree(Tables(TblName).DataTable,Columns)
Dim ArrColName() As String = Columns.Split("|")
For i As Integer = 0 To Ubound(ArrColName)
    If Tables(TblName).DataTable.DataCols(ArrColName(i)).IsDate Then
        For Each Nd As WinForm.TreeNode In TvwCtl.AllNodes
            Dim idx As Integer = nd.Text.IndexOf(" ")
            If idx >= 0 AndAlso Nd.Level = i Then Nd.Text = Nd.Text.SubString(0,Nd.Text.IndexOf(" "))
        Next
    End If
Next
TvwCtl.Nodes.Insert("显示所有行",0)
TvwCtl.Form.ResumeRedraw

 你全局代码那里，要定义MySheet、MyBook才行啊。
