tessera_html #

HTML export for the tessera pivot-table engine.

HtmlCubeExporter writes a CubeLayout (the expanded rows and columns exactly as shown) as a <table>: merged group headers in the "rotated L" shape, one column per aggregate under each column entry, subtotals on the group's own row, classes per cell kind and level, and a stylesheet from the engine's CubeExportTheme — embedded in a <style>, inlined on the cells (for e-mail), or left out so the page's CSS takes over. Labels and numbers come from TesseraStrings, so the export is localized like the widgets.

Pure Dart, no Flutter — servers, CLIs and apps alike.

import 'package:tessera_html/tessera_html.dart';

final html = HtmlCubeExporter(
  strings: TesseraStrings.forLanguage('hu')!,
  theme: CubeExportTheme.brand(primary: 0xFF00695C),
).export(cube.layout, title: 'Sales by region');

export returns the HTML as a String (a whole document, or a fragment with standalone: false).

Example #

example/main.dart reads example/sales.csv, builds a region/country × year/quarter cube with every region expanded and writes it as sales_pivot.html:

dart run example/main.dart [input.csv] [output.html]
