主题：名称为"统计表1"的table不存在？

Dim cmd As New SQLCommand
Dim dt As DataTable
cmd.C
cmd.CommandText = "Select  客户名称,数量_本次交*单价 As [金额] From {出库单主表} Inner JOIN {出库单明细} ON {出库单明细}.[出库单号] = {出库单主表}.[出库单号]"
dt = cmd.ExecuteReader()
'对临时进行分组统计
Dim b As New CrossTableBuilder("统计表1",dt)
b.HGroups.AddDef("客户名称")
b.Totals.AddDef("金额")
b.HorizontalTotal = True
b.VerticalTotal = True
b.Build()
MainTable = Tables("统计表1")

名称为"统计表1"的table不存在？何故？求解...
