Table gallery

Ready-made c2-table setups: columns and formats, sorting and selection, toolbars and footers, states, and looks from a hairline report to a trading terminal.

Columns and data

Every card is a rows array plus a set of c2-table-column children: width takes any grid track, align moves the text, format runs the value through Intl (number, currency, percent, date, datetime, time), and pinned sticks a column to either edge while the rest scrolls. A cell value is text, so a column is dressed up from CSS: ::part(cell-content-status) is the text of the status column and takes a pill as well as any badge would. Put a component in a cell with a renderCell function from script.

Sorting and selection

sortable makes every header a sort control and sort="field:asc" sets the starting order; multi-sort lets a shift-click add a second key. Selection is single or multiple, with checkbox-selection for a leading checkbox column, and value holds the selected row keys — ;-separated in markup.

The toolbar and footer slots are yours, and they are the natural place for the rest of the library: c2-text-field for a search, c2-select for a filter, c2-button and c2-icon-button for actions, c2-badge for a count. Both bars stay outside the scrolling body and are hidden until something is slotted into them; --c2-table__toolbar--* and --c2-table__footer--* set their padding, background and divider.

A c2-pagination in the footer is wired up rather than decorative: the table pages its rows and drives the pager’s page, page-size and total-items, so the card below works with nothing but the two elements. With a dataSource the same markup pages server-side, one request per page.

Toolbar: title and actions
Toolbar: search
Toolbar: filters
Footer: totals
Footer: pager

States

loading shows a spinner until the data lands — or whatever you slot into loading — error replaces the body with a message and a way out, and an empty rows array shows empty-message or the empty slot. Give the host a height and the body scrolls inside it; past virtual-threshold rows it virtualizes on its own.

Looks

Same data, different surface. The table is one CSS grid, so a look is only variables: --c2-table--* for the frame, --c2-table__header--* and --c2-table__header-cell--* for the head, --c2-table__row--* with its __odd, __hover and __selected states, and --c2-table__cell--* for the body. Each cell also carries a part named after its column — ::part(cell-pct) — so one column can be styled on its own.
