Export "Sales Daily / Weekly / Monthly Report" to Excel with Java (Formula & Calculated Reports)
Formula & Calculated ReportsScene 0001
Daily sales detail, computing Amount = Quantity × Unit Price per row with a total row at the end. Implemented declaratively in pure XML — no Java business code required.
About this demo
This demo exports the "Sales Daily / Weekly / Monthly Report" workbook: 1 data sheet(s); MAPPING over 5 columns (日期, 商品, 数量, 单价, 金额), 6 formula(s), 1 style rule(s). On the Java side it builds 4 data rows and calls exportSalesDailyReport() once — everything else is driven by the config.
It belongs to the "Formula & Calculated Reports" group: FORMULAS — inline expressions and aggregate functions such as Quantity × Unit Price or Balance = Receivable − Received, with SUM totals on the last row.

}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("mintFresh", 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.
