Single and multi-column

Single and multi-column sorting
Sorting is the first interaction most people try on any JavaScript data grid, so it has to read correctly from a single click: ascending, then descending, then unsorted, with an arrow in the header showing which. Lattice Grid drives this through sort.set([{ col, dir }]), taking one entry for a single sort or several for a multi-column sort, ordered by priority. Click a header to sort by that column alone; shift-click a second header to add it as a tiebreaker without disturbing the first. With more than one column active, each sorted header shows a small order index beside its arrow, so a user can see the grid is sorted by region first and revenue second, rather than guessing from result order.
A developer reaches for the explicit sort.set call when restoring a saved view, applying a default sort on load, or driving sort from a toolbar control outside the header. Sort state is a plain array of { col, dir } pairs, so it serialises directly to a URL parameter or a saved-view record and reapplies on the next visit without replaying clicks. Sorting runs against the full row set, not only the rows currently rendered, so a reorder in a grid of a million rows repositions the visible window without re-rendering rows that never left the store.
How do you sort by more than one column in a JavaScript data grid?
Shift-click a second column header after sorting the first; Lattice Grid adds it as a secondary sort key and shows an order index in each active header. Programmatically, call sort.set([{ col: 'region', dir: 'asc' }, { col: 'revenue', dir: 'desc' }]) to set the same multi-column order directly, useful when restoring a saved view or applying a default sort on load.
