Export "R&D Project Milestone Progress" to Excel with Java (Styled & Formatted Reports)

JQuick-ExcelStyled & Formatted Reports

Styled & Formatted ReportsScene 0075

Registers planned and actual hours per milestone, computing Hour Variance = Planned - Actual and Hour Achievement Rate = Planned / Actual, with the last row summarizing total planned hours, total actual hours, total variance and the overall achievement rate; the milestone with the lowest achievement rate is marked in red. Implemented declaratively in pure XML — no Java business code required.

About this demo

This demo exports the "R&D Project Milestone Progress" workbook: 1 data sheet(s); MAPPING over 7 columns (里程碑阶段, 负责人, 计划工时, 实际工时, 偏差工时, 工时达成率, 状态), 16 formula(s), 1 style rule(s). On the Java side it builds 6 data rows and calls exportProjectMilestoneProgress() once — everything else is driven by the config.

It belongs to the "Styled & Formatted Reports" group: STYLE and conditional formatting: themed headers, zebra striping, highlighted total rows and threshold-based colouring of abnormal cells.

What you can copy from this page

  • The complete Java test class (65 lines, runnable as-is)
  • The complete XML config (34 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("jade", rows, os);
JQuickFactory factory = new JQuickXmlFactory(parser, XML);
Style0075ProjectMilestoneProgressService service = factory.createApi(Style0075ProjectMilestoneProgressService.class);

XML config · 0075_style_project-milestone-progress.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.
