Notes on building a data grid: what we measured, why it is built the way it is, and what we got wrong.https://www.latticegrid.dev/en-gbhttps://www.latticegrid.dev/blog/column-knows-it-holds-metres/https://www.latticegrid.dev/blog/column-knows-it-holds-metres/In most grids a unit is a formatter, and a formatter is a lie that shows the moment someone sorts. Lattice Grid makes a quantity a data type, so the column stays a number.Sat, 29 Aug 2026 00:00:00 GMTdevelopertypesunitsTony Goodchildhttps://www.latticegrid.dev/blog/the-table-is-the-schema/https://www.latticegrid.dev/blog/the-table-is-the-schema/htmx renders the table on the server; Lattice Grid upgrades it into a live grid in place, columns and rows read straight from the markup, and it survives htmx swaps.Wed, 26 Aug 2026 00:00:00 GMTintegrationhtmxTony Goodchildhttps://www.latticegrid.dev/blog/swap-the-import/https://www.latticegrid.dev/blog/swap-the-import/A compatibility layer gives Lattice Grid the shape of dhtmlx's dhx.Grid, so the constructor, the data and selection namespaces and the events keep working.
