Export "Office Supplies Requisition Ledger" to Excel with Java (Merge & Grouped Reports)

JQuick-ExcelMerge & Grouped Reports

Merge & Grouped ReportsScene 0092

Groups office-supply requisitions in two levels (Requisitioning Department → Supply Name), computing Amount = Quantity × Unit Price per row; a subtotal row follows each department and a grand total for all departments appears in the last row; the requisitioning-department column is vertically merged into one block. Java only groups and pre-processes the rows; all statistics and layout are declared in XML.

Office Supplies Requisition Ledger — Merge & Grouped Reports

About this demo

This demo exports the "Office Supplies Requisition Ledger" workbook: 1 data sheet(s); MAPPING over 6 columns (领用部门, 领用人, 用品名称, 数量, 单价, 金额), 13 formula(s), 5 style rule(s). On the Java side it only builds the data and calls exportOfficeSuppliesLedger() 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.

What you can copy from this page

  • The complete Java test class (95 lines, runnable as-is)
  • The complete XML config (40 lines: mapping, formulas, styles, charts and every other rule)
  • The exported xlsx file (real output, comparable with the preview above)

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("forestGreen", rows, os);
JQuickFactory factory = new JQuickXmlFactory(parser, XML);
Merge0092OfficeSuppliesLedgerService service = factory.createApi(Merge0092OfficeSuppliesLedgerService.class);

XML config · 0092_merge_office-supplies-ledger.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.
