Table

Grouped Header

A table with a two-storey header: the top row groups columns by year with colspan, the bottom row names the columns inside a year, and the first cell is merged with rowspan.

React + Tailwind, shadcn-compatible: press “Copy for AI” and your Cursor or Claude Code agent installs it with the shadcn CLI.

What you can change

  • the groups and their columns through groups
  • the rows and their values through rows
  • the first column caption through leadTitle

A link for your AI agent: preview, code and instructions.

FAQ

How do I add Grouped Header with Cursor or Claude Code?
Press “Copy for AI” on this page and paste it into your agent's chat. The instruction contains the shadcn CLI install command, the dependencies and what to keep, so the agent installs this exact component instead of recreating a lookalike.
What does Grouped Header depend on?
No npm packages beyond React and Tailwind CSS.
What can I change in Grouped Header?
Adapt: the groups and their columns through groups; the rows and their values through rows; the first column caption through leadTitle. Keep as installed: the local --vibeui-table-014-* palette — do not swap it for your theme tokens; scope="colgroup" on the upper header row: without it a number loses the year it belongs to; rowSpan={2} on the first cell: otherwise the row-header caption hangs over nothing.
Is Grouped Header free?
Yes. The preview is open without an account; with a free account you can copy up to 20 components a month.

Technical notes

The component is self-contained: one file, no dependencies, its palette in the --vibeui-table-014-* variables. A server component: no hooks. The upper header cells are declared as th scope="colgroup" with colSpan — without colgroup a screen reader will not tie a number to its year, and the two "Plan" columns become indistinguishable. The first cell gets rowSpan={2} and stays a th scope="col". The flat column list is assembled from the groups with flatMap, so the table body is drawn in a single pass and the cell order cannot drift from the header. The boundary between groups is drawn with data-edge rather than nth-child: the rule survives adding a column.
