参照网上的模糊查询帮助，新建了个模糊查询窗口（窗口2），在输入框中输入内容，表中不显示文字，但是能够筛选出符合条件的行数，就是没显示文字，大家看看这段代码错在哪里？

Dim t As Table =Tables("窗口2_Table1")
Dim st,ls ,py,Lm,str,Lss As String
Dim Ts As String() = {"第一列","第二列","第三列","第四列"}
Dim drs As New List(of DataRow)

st = e.sender.Text.ToUpper
drs = DataTables("表A").Select("第一列 > \'\'")
If drs.count > 0 Then
    If st IsNot Nothing Then
        For Each Lm In Ts
            For Each dr As DataRow In DataTables("表A").DataRows
                py = GetPY(dr(Lm),True)
                If dr(Lm).IndexOf(st)> -1 OrElse py.IndexOf(st) > -1 Then
                    If Ls Is Nothing Then
                        Ls = dr("_Identify")
                    Else
                        If Ls.IndexOf(dr("_Identify")) = -1 Then
                            ls+= "," &  dr("_Identify")
                        End If
                    End If
                   
                    If Lss Is Nothing Then
                        Lss = dr(Lm)
                    Else
                        If Lss.IndexOf(dr(Lm)) = -1 Then
                            Lss+ = "|" & dr(Lm)
                        End If
                    End If
                End If
            Next
        Next
        If ls IsNot Nothing Then
            Ls ="[_Identify] In(" & Ls & ")"
            Ls="select 第一列,第二列 ,第三列,第四列 from{表A} where " & Ls
            t.Fill(Ls,True)
            e.sender.ComboList = Lss
        End If
    End If
End If

没有看懂你的问题，不过既然数据都加载了，用筛选就行了，何必用Fill，这样开销很大，所以最后一段应该改为：

If ls IsNot Nothing Then
    Ls ="[_Identify] In(" & Ls & ")"

     Tables("窗口1").Filter = ls
    e.sender.ComboList = Lss
End If
