Sub-heading rows, collapsible sections and a Spec Sheet pattern
Tables can now be split into named sections for spec sheets and other structured layouts.
- Sub-heading rows — mark any row as a sub-heading from the data-grid selection toolbar; the heading text comes from the row's first filled cell and follows the row through insert, move, duplicate and delete operations.
- Two heading displays — a full-width banner row, or a side-label column that spans its whole section (classic spec-sheet look), with optional heading background and text colours (text defaults to the table accent colour).
- Collapsible sections — optional visitor expand/collapse toggle per section, with a start-collapsed setting.
- Sensible guardrails — section tables suspend sorting and pagination so groups stay together, position numbering skips heading rows, and table search keeps headings visible while filtering data rows.
- Spec Sheet block pattern — ready-made pattern in the Data & Visualizations category with seven pre-built collapsible side-label sections (Network, Launch, Body, Display, Platform, Memory, Battery).
