主题：这段代码里被查询的对象是 数值类的应该怎么改呢？

Dim txt As String = e.Form.Controls("TextBox1").Text
Dim tbl As Table = Tables("窗口1_Table1")
If txt = "" Then
    tbl.Filter = ""
Else
    数值 = "'*" & txt & "*'"
    tbl.Filter = "客户ID Like " & txt & " Or 公司名称 Like " & txt & " Or 地址 Like " & txt & " Or 联系人 Like " & txt
End If
