Crystal reports 基于条件抑制“详细信息”区域中的线对象

我用的是Crystal Report 2008。我有一个报告结果，其中包括超过1页和1组。样本结果如下：

第1页：
>#项目编号价格
>\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu
>1项A001$1000
>2项A002$1000
>3项目A003$2000
>\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu
>总额：4 000美元

第2页：
>#项目编号价格
>\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu
>1项B001$2000
>2项B002$1500
>3项B003$2000
>\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu
>总额：5 500美元

现在我想在每一行之间插入一行，如下所示：
（据我所知，用户无法设置要抑制的线条对象的条件，因此我在详细信息b中添加了线条） 第1页：

我尝试过在“RecordNumber>=Count（{ItemNo.}）”时抑制，但第二页的RecordNumber没有重置，所以所有细节b都将在第2页中抑制。
如何设置条件以抑制每个组中最后一条记录的详细信息b？

查找下面的解决方案

为“详细信息”部分中的字段创建一个运行总计，运行总计应如下所示

1. Field to summarize should be Database Field, Type of summary should be "Count".

2. Evaluate for each record.

3. Reset for change of Group

现在你得到了该组的记录数

要取消最后一条记录的行，请转到详细信息b取消公式编辑器，并给出以下代码。使用insert summary（插入摘要）统计“详细信息”部分中归档的记录

IF（Count（field，Group}）=运行总数）
那是真的
否则为假

一旦计数（它给出记录的一个值计数）等于运行总值，该行将被抑制

这是经过测试的代码，适用于我。

使用此规则抑制“详细信息B”部分：

onlastrecord or next(table.groupfield)<>table.groupfield

onlastrecord或next（table.groupfield）table.groupfield

使用此规则抑制“详细信息B”部分：

onlastrecord or next(table.groupfield)<>table.groupfield

onlastrecord或next（table.groupfield）table.groupfield
