Tables

9 things a dvt table can do, each declared in the JSON spec.

Column formats, sorting and wrapping, conditional formatting, colour scales, ten in-cell visual kinds in the schema (eight render today), grouping with subtotals, column spanners, pivots, footnotes and warehouse-comment headers, and row and cell actions. Every one is a property of the same table panel spec the engine validates, so an agent can write it and a reviewer can read it.

Columns and formats

The column vocabulary: fields, labels, number/date formats, sort, and width.

Table

Render sparklines, bars, bullets, icons, and more inside table cells.

Conditional formatting

Highlight rows and cells by rule, including topN ranking and stopIfMatched precedence.

Colour scales

Grouping, spanners and pivots

Grouped rows with subtotals, multi-level column headers, and pivot tables.

Cross-tabulate a measure across row and column fields with totals.

Grouping and subtotals

Nest rows by field with collapsible groups, per-group subtotals, and a grand total.

Column groups

Span a shared header row over several contiguous columns, nested as deep as needed.

Notes and actions

Footnotes, source attribution, warehouse-sourced headers, and row-level actions.

Notes and metadata

Attach numbered footnotes, a source line, and warehouse-sourced headers to a table.
