主题：什么原因呢

分别生成表格，是否正常？

Dim bd1 As New sqlGroupTableBuilder("统计表1","pzk")
bd1.Groups.AddDef("成本_所属项目","项目分类")
bd1.Groups.AddDef("成本_提供方","材料供应商")
bd1.Totals.AddDef("成本_金额","主材料结算_金额")
bd1.Totals.AddDef("成本_数量","主材料结算_数量")
bd1.Totals.AddExp("成本_摘要", "成本_摘要", AggregateEnum.max)
bd1.Build
Dim bd2 As New sqlGroupTableBuilder("统计表2","pzk")
bd2.Groups.AddDef("付款_所属项目","项目分类")
bd2.Groups.AddDef("付款_收款方","材料供应商")
bd2.Totals.AddDef("付款_金额","已付金额")
bd2.Filter  = "付款_类别 = '主材料'"
bd2.Build

我这样测试没问题，请做个例子发上来测试

Tables("表A").grid.styles.Normal.Border.Color = Color.Red
Tables("表A").grid.styles.Normal.Border.Style = 1
Tables("表A").grid.styles.Normal.Border.width = 2
Tables("表A").grid.styles.Normal.Border.Direction = 0 '0-2
