首先,记录按表组件显示在表中,但不在报表中显示.

结果如下:

总部列显示了每个季度的总和.

重复字段值时不会打印它们.

问题是如何对sumquarter的列进行分组,以便每行中第一个打印的重复值加入下一个重复值,成为单个单元格,直到它满足非重复值?

你可以在图像中看到它.下面是表格显示的图像,我喜欢的解决方案是将这3个月的总和分组到一个单元格中.

这是图像:

在这个示例中,我DetailYear列的乐队中使用了两个元素:一个textField只有垂直边框和printWhenExpression: "$V{yearGroup_COUNT} == 1"属性(我只为整个yearGroup显示一次),一个staticText没有任何文本,只有垂直边框.

我在Detail乐队的乐队中使用了三个元素Quarter Sum:
一个textField只有垂直边框和printWhenExpression: "$V{quaterGroup_COUNT} == 1"属性(我只为整个quaterGroup显示一次),一个staticText没有任何文字,只有垂直边框和line水平绘制元素与printWhenExpression: "$V{quaterGroup_COUNT} == 1"财产边界.
