Two BaseTable instances on the same page (e.g. multiple base embeds in
one document) shared the same global jotai atoms for activeViewId,
editingCell, property menu state, and row selection. Each instance's
useEffect that synced activeViewId would clobber the other's value
every render, pinning React into a "Maximum update depth exceeded"
loop.
Convert every UI atom in base-atoms.ts to an atomFamily keyed by pageId
so each base owns its own scope, and thread pageId through the grid
component tree (GridRow, GridCell, GridHeaderCell, RowNumberCell,
RowNumberHeaderCell, PropertyMenuContent) plus useRowSelection so each
consumer reaches the per-base atom. use-base-socket already had pageId
in scope; its store.get/store.set calls now resolve through
selectedRowIdsAtomFamily(pageId) too.
Split the unified .gridWrapper into a sticky band (containing column
headers, plus banner + toolbar in inline) and a body grid that owns
horizontal scroll. The band's vertical sticky anchor is automatic CSS:
the table's scrollport in standalone, the page in inline. A small
useHorizontalScrollSync hook mirrors body scrollLeft onto the header
and turns wheel-on-header into pan-on-body.
As a child of .grid with grid-column: 1/-1, the button took the full
row width and the sticky-left offset got swallowed by the grid layout
— it scrolled along with the cells instead of anchoring to the left.
Move it to a sibling of .grid inside .gridWrapper, restyle as a
small inline-flex chip with width: max-content. Sticky-left now
keeps it pinned to page-content-left while the user scrolls
horizontally, matching the toolbar.
Add padding-bottom: 6px on .gridWrapper and a small vertical margin
on the button so the horizontal scrollbar no longer overlaps it.
Bring back the leftward extension via negative margin-left so the
scroll viewport reaches AppShell.Main's left edge, then offset the
.grid with padding-left = extendLeft so the first cell still lines
up with page-content on load. The extended area becomes scrollable
empty space the user can pan into — same shape as Notion's inline
databases.
Done with one new CSS var (--embed-grid-pad-left) consumed by the
.grid in grid.module.css. Standalone full-page bases never set the
var, so it's a no-op there.
Removing the leftward extension. With negative margin-left, the
grid grew leftward past page-content and the first column appeared
near the sidebar edge on load — wrong; Notion keeps the first column
aligned with page text. Drop margin-left and the extendLeft
calculation; only extend rightward toward AppShell.Main's right edge.
Leftward viewport extension (so frozen columns can lock at the
sidebar edge during scroll) becomes meaningful once we add frozen
columns. Deferred until that feature lands.
The previous approach (position: relative + explicit width +
inset-inline-start) didn't physically grow the box in some flex
contexts, so the grid stayed at the parent's width. Switch to
negative margin-left / margin-right on the grid wrapper only —
with width: auto, the rendered width becomes parent + |margin|,
extending the box past the parent without any positioning hacks.
The toolbar keeps its natural parent-constrained width (no extension)
so it stays aligned with the page text above. Two CSS vars,
--embed-extend-l / --embed-extend-r, are computed on mount + on
ResizeObserver from the wrapper and the closest wider ancestor.
When a base is embedded inline in a doc page, measure the parent
container's available area and extend toolbar + grid sections to fill
it via CSS variables (--embed-width / --embed-shift / --embed-pad).
Inner content is re-padded so toolbar buttons and the first column
visually align with the page text, while the box itself reaches the
viewport edges for horizontal scroll headroom on wide databases.
Sticky inset-inline-start keeps the toolbar pinned to the page-content
edge during horizontal scroll. Standalone full-page bases are
unaffected (the embedded prop defaults to false).
Mounts useBaseRowsCountQuery alongside the rows query so the count is
fetched eagerly and the cache is warm by the time the toolbar consumes
it. Gating on `currentUser` (not just `base`) ensures the persisted
view-draft has hydrated from localStorage before the first count fires
— otherwise a post-refresh count races ahead of the user's saved
filter and ships without it.
Browser overflow-anchor silently bumped scrollTop by one page's worth
of pixels every time a new page of rows committed — anchoring on the
AddRowButton that sits below paddingBottom. This kept the near-bottom
threshold satisfied and re-fired onFetchNextPage indefinitely, even
after the user released the scrollbar. Disabling scroll anchoring on
the grid scroll container stops the browser from adjusting scrollTop
in response to content growth.
