将几个相同的值字段分组到单个单元格中 [英] Group several same value field into a single cell
问题描述
首先，记录按表格组件显示在表格中，但不在报告中显示。
First of all, the records are shown in the table by table component but not in the report one.
结果如下所示：

总和列显示每年每季度的总和。
The sumquarter column shows the sum of each quarter in year.
重复该字段的值时不会打印它们。
They are not printed when it repeated the value of the field.
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？
The question is how to group the column of sumquarter, so that the first printed repeated value in each row to join the next repeated value to become a single cell until it meets the non-repeated value?
您可以在图片中看到它。
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。
You can simply see it in an image. Below is the image that the table shows and the solution that I preferred is to group those 3 months of sum into a single cell.

结果将是（pdf格式）：
The result will be (in pdf format):
在此示例中，我使用了两个元素 频段：年列的详细信息
one textField 只有垂直边框且 printWhenExpression：$ V {yearGroup_COUNT} == 1 属性（我只为整个 yearGroup 显示一次）和一个 staticText 没有任何文字，只有垂直边框。
In this sample I've used two elements in the Detail band for the Year column:
one textField with only vertical borders and with printWhenExpression: "$V{yearGroup_COUNT} == 1" property (I'm show it only once for the whole yearGroup) and one staticText without any text and with only vertical borders.
我在 详细信息季度总和列的c $ c> 范围：
一个 textField 只有垂直边框且 printWhenExpression：$ V {quaterGroup_COUNT} == 1 property（我只为整个 quaterGroup 显示一次），o ne staticText 没有任何文字，只有垂直边框， 行 使用 绘制水平边框的元素：printWhenExpression：$ V {quaterGroup_COUNT} == 1 属性。
I've used three elements in the Detail band for the Quarter Sum column:
one textField with only vertical borders and with printWhenExpression: "$V{quaterGroup_COUNT} == 1" property (I'm show it only once for the whole quaterGroup), one staticText without any text and with only vertical borders and the line element for drawing horizontal border with printWhenExpression: "$V{quaterGroup_COUNT} == 1" property.
