Export "Expense Reimbursement Form" to Excel with Java (Merge & Grouped Reports)
Merge & Grouped ReportsScene 0013
Reimbursement detail rows computing Reimbursable Amount = Amount - Self-Paid Amount, with a total row at the end. Implemented declaratively in pure XML — no Java business code required.
About this demo
This demo exports the "Expense Reimbursement Form" workbook: 1 data sheet(s); MAPPING over 5 columns (费用类型, 发生日期, 金额, 自付金额, 可报销金额), 8 formula(s), 2 style rule(s). On the Java side it builds 4 data rows and calls exportExpenseReimbursement() 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 (62 lines, runnable as-is)
- The complete XML config (27 lines: mapping, formulas, styles, charts and every other rule)
- The exported xlsx file (real output, comparable with the preview above)

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("plum", rows, os);
JQuickFactory factory = new JQuickXmlFactory(parser, 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.
