What it means
Layout decides the outer frame first: width, height, row height, header height, sticky header, and optional root-level class/style hooks.
Foundation guide
Layout data grid documentation
Layout sets the grid frame: width, height, row height, header height, sticky header behavior, and optional root class/style hooks.
When to use it
Use it when the same grid needs one frame for dense work and another for slower review. Reach for layout props before rewriting columns just to make a page feel tighter or more spacious.
Implementation notes
Keep width, height, row height, header height, sticky header, and root shell hooks together under `layout`. Pick the frame first, then let columns and other features adapt to that frame.
Relevant API
Start with layout.width, layout.height, layout.rowHeight, layout.headerHeight, layout.stickyHeader, layout.className, layout.style. Open the live API reference for types and defaults.
