请问，如何把两组代码产生的临时表数据和在一个表中？

Dim g As New GroupTableBuilder("统计表1", DataTables("坯布输入"))

g.Groups.AddDef("年")

g.Groups.AddDef("月")

g.Groups.AddDef("产品名称")

g.Totals.AddDef("匹数", "下机坯布_累计")

g.Totals.AddDef("总长", "长度_累计")

g.Totals.AddDef("织造车间扣分", "扣分_累计")

g.Totals.AddDef("总重", "重量_累计")

b.Decimals = 2

g.FromServer = True

g.Build()

MainTable = Tables("统计表1")

Dim b As New GroupTableBuilder("统计表2", DataTables("坯布输入"))

b.Filter = "日期 >= #" & Date.Today & "# “

b.Groups.AddDef("年")

b.Groups.AddDef("月")

b.Groups.AddDef("产品名称")

b.Totals.AddDef("匹数", "下机坯布_本日")

b.Totals.AddDef("总长", "长度_本日")

b.Totals.AddDef("织造车间扣分", "扣分_本日")

b.Totals.AddDef("总重", "重量_本日")

b.Decimals = 2

b.FromServer = True

b.Build()

MainTable = Tables("统计表2")
