java - DynamicJasper:一页中包含3个报告部分

我想生成一个报告作为此设计：

2013                                           2012                       2011
                      NewCol1    NewCol2
Dept       Item      col1 col2 col3 col4       col1 col2 col3           col1 col2 col3

Area1
1          A         1    2     4     5         1    2    3              1    2    3

1          A         1    2     4     5         1    2    3              1    2    3

1          A         1    2     4     5         1    2    3              1    2    3


Area2

1          A         1    2     4     5         1    2    3              1    2    3

1          A         1    2     4     5         1    2    3              1    2    3

1          A         1    2     4     5         1    2    3              1    2    3

我使用DynamicJasper并将2013、2012和2011视为3个不同的子报表，并尝试
生成它。但是我在不同行中获得了2012年和2011年的数据。有人可以帮助我使用DynamicJasper设计上述布局吗？ 2013、2012和2011是同一行中的三个不同标题。

public class LayoutDesigner
{
    public DynamicReport buildReportLayout(List<Mylist> list)
               /* List is the Java bean which contains all the data to be exported.*/

            throws ColumnBuilderException, ClassNotFoundException
    {
        int colIndex = 1;
        int colSpanSize;
        FastReportBuilder drb = new FastReportBuilder();

        AbstractColumn columnArea = ColumnBuilder.getNew()
                            .setColumnProperty(ReportDetails.COLUMN_PROPERTY[0], String.class.getName()) /* ReportDetails conatins header and properties to be mapped.. */
                            .setFixedWidth(true)
                            .setTitle(ReportsDetails.COLUMN_PROPERTY[0]).setWidth(new Integer(100))
                            .build();
        AbstractColumn column1 = ColumnBuilder.getNew()
                            .setColumnProperty(ReportDetails.COLUMN_PROPERTY[1], String.class.getName())
                            .setFixedWidth(true)
                            .setTitle(ReportsDetails.COLUMN_PROPERTY[1]).setWidth(new Integer(100))
                            .build();
                            ........../*  Defining other Abstrct Columns */

        GroupBuilder gb = new GroupBuilder();
        DJGroup djb = gb.setCriteriaColumn((PropertyColumn) columnArea)

                        .addFooterVariable(column1,DJCalculation.SUM)
                        ........./*   added all essential variables */
                        .setGroupLayout(GroupLayout.VALUE_IN_HEADER)
                        .build();


        drb.addColumn(columnArea);
        drb.addColumn(column1);
        ...

        drb.addGroup(djb);

        /*  I grouped and now doing column span for clubbing col1 col2  under NewCol1. Also col1 col2 under NewCol2. This is also working.
         Problem here is I want one more layer of span to club NewCol1 and NewCol2 under 2013, but this is not working and I am not sure how to do.
         So I thought of 2 reports one containing 3 diferent columns (2013,2012 and 2011)  and another remaining data. But just with 3 different columns I cant show it, since without a column property, I cant define COlumns in a report..*/

        for (int i = 0; i < LAYOUT.length; i++)
        {
            if(ReportDetails.LAYOUT[i].equalsIgnoreCase(ReportDetails.LAYOUT[3]))
            {
                colSpanSize=2;
            }
            else
            {
                colSpanSize=1;
            }
            drb.setColspan(colIndex, colSpanSize,String.valueOf(ReportDetails.LAYOUT[i]));
            colIndex = colIndex + colSpanSize;
        }
        DynamicReport dr = drb.build();
        return  dr;
    }
}

最佳答案

为了设计以上，您可以做的是：


根据区域创建报告组
将区域标题放入区域组标题中
将所有其他标题放在列标题中
在明细栏中并排放置Dept，Item和3个子报表


我也附上了屏幕截图。
