主题：求帮助，我想把组合框字符串当成表名用

Dim wfc As WinForm.ComboBox = e.Form.Controls("ComboBox1")

Dim cp As String 

cp = wfc.Value

Dim jb As New SQLJoinTableBuilder("查询表1",cp)

jb.Connection 链接名 Name = "Sale"   

jb.AddTable(cp,"产品ID","产品","产品ID")

jb.AddTable(cp, "客户ID","客户","客户ID")

jb.AddExp("产品","产品名称")

jb.AddCols("日期", "数量","单价")

jb.AddExp("金额","数量 * 单价")

jb.Filter="{客户}.客户ID='C01'"

jb.Build()

MainTable = Tables("查询表1")
