data-table
by Criptso
The house standard for any multi-column list, in any app and any stack: sticky high-contrast header, click-to-sort, a per-column menu (filter by value, search, date range, derived columns), frozen first column, add-column that reaches the database, smart widths with Excel-style wrap, a 3-line cap per cell with hover reveal, resizable rows and columns, right-aligned tabular figures, and one date format. Use BEFORE building or changing any table, grid, or list with more than one column — dashboards, admin screens, inventory, reports, invoices, anything with rows. Also use when a table already exists and is being reviewed, extended, or restyled, and whenever someone says the list should behave "like Excel" or "like Sheets". Ships a browser-driven verification suite that is the done-gate: a styled dead control photographs exactly like a live one.
