Export "Grouped Sales Aggregation" to Excel with Java (Merge & Grouped Reports)

JQuick-ExcelMerge & Grouped Reports

Merge & Grouped ReportsScene 0104

Lists each store's Q1-Q4 sales grouped by region, with the region-name column vertically merged into one block to visually group the stores of the same region. Java only groups and pre-processes the rows; all statistics and layout are declared in XML.

About this demo

This demo exports the "Grouped Sales Aggregation" workbook: 1 data sheet(s); MAPPING over 6 columns (大区, 门店, 一季度, 二季度, 三季度, 四季度), 4 style rule(s). On the Java side it builds 6 data rows and calls exportGroupSalesAggregate() once — everything else is driven by the config.

It belongs to the "Merge & Grouped Reports" group: MERGE group blocks with SUBTOTAL/TOTAL rows: each group column merges into one vertical block, every group closes with a subtotal and the report ends with a grand total.

Minimal invocation (4 lines)

The core is these four lines: hand the rows to the parser, the parser to the factory, get a typed Service and call it. Copy them straight into your project.

// rows 由业务代码构造（List<JQuickRow>），os 为输出流，见下方完整源码
JQuickParseHandler parser = new JQuickExcelExportXmlParseFactory("terracotta", rows, os);
JQuickFactory factory = new JQuickXmlFactory(parser, XML);
Merge0104GroupSalesAggregateService service = factory.createApi(Merge0104GroupSalesAggregateService.class);

XML config · 0104_merge_group-sales-aggregate.xml

Formats (FORMAT), formulas (FORMULAS) and styles (STYLE) are all declared in this XML, fully decoupled from the Java code. The full config is below — copy it as-is.
