Featured

• Why the World Needed Another Grid - Every framework era gets the data grid it deserves - jqxGrid for the jQuery age, the grids that followed for the Angular and React age, and now a grid built natively on Svelte 5 runes.

Tutorials

• A Sticky Summary / Footer Row in SvGrid - Show always-visible totals at the bottom of your data grid - column footers with sums and averages that stay pinned while rows scroll.
• Sync Grid State to the URL in Svelte - Make a data grid's sort, filter, and page state shareable and bookmarkable by syncing it to the URL query string in SvelteKit.
• Render Your First Svelte Data Grid in Under 5 Minutes - A step-by-step guide to adding a fast, accessible data grid to a Svelte 5 app with SvGrid - data, columns, and the features you get for free.
• Column Definitions in SvGrid - Fields, Accessors, and Formatting - Everything a Svelte data grid column can do - field accessors, computed values, locale-aware formatting, alignment, and custom cells.
• Multi-Column Sorting in a Svelte Data Grid - Enable single and multi-column sorting in SvGrid, observe sort state, and drive server-side ordering from the same UI.
• Excel-Style Filtering for Your Svelte Data Grid - Add per-column filter menus, a filter row, and global search to SvGrid - plus how to drive filtering from the server.
• Inline Editing with Validation in SvGrid - Make cells editable in your Svelte data grid, choose the right editor type, validate input, and save changes safely.

• Master-Detail Rows - Expandable Detail Panels in SvGrid - Build expandable rows that reveal a detail panel - a nested grid, a chart, or a form - using SvGrid's row expanding feature.
• Displaying Tree Data and Hierarchies in SvGrid - Render parent-child hierarchies - org charts, file trees, category trees - in a Svelte data grid with expandable tree rows.
• Server-Side Data - Pagination, Sorting, and Filtering on the Backend - Drive a Svelte data grid from your API. Let SvGrid own the UI state while your server owns paging, sorting, and filtering.
• Row Selection and Clipboard Copy-Paste in SvGrid - Add checkbox selection, range selection, and Excel-compatible copy-paste to your Svelte data grid.
• Custom Cell Renderers with Svelte Snippets - Render badges, progress bars, avatars, and action buttons inside SvGrid cells using Svelte 5 snippets and renderSnippet.
• Pinned (Frozen) Columns for Wide Svelte Data Grids - Keep key columns visible while scrolling horizontally by pinning them left or right in SvGrid.
• Column Resizing and Reordering - Let Users Shape the Grid - Give users drag-to-resize and drag-to-reorder columns in SvGrid, and persist their layout between sessions.
• Spreadsheet-Style Cell Range Selection in SvGrid - Let users drag to select rectangular cell ranges, then copy, sum, or act on them - the spreadsheet interaction your Svelte grid needs.
• Conditional Formatting - Color Cells by Their Value - Highlight negatives, flag thresholds, and build heatmaps in a Svelte data grid with value-driven cell styles in SvGrid.
• Pagination Patterns - Offset, Cursor, and Infinite Scroll - Choose the right paging strategy for your Svelte data grid and wire offset, cursor, and infinite-scroll patterns to SvGrid.
• Real-Time Grids - Live WebSocket Updates in SvGrid - Stream live data into a Svelte data grid over WebSockets without dropping frames, using batching and stable row identity.
• Optimistic Updates - A Grid That Feels Instant - Make edits in your Svelte data grid feel immediate by updating the UI first and reconciling with the server, with clean rollback on failure.
• Locale-Aware Number, Date, and Currency Formatting - Display numbers, dates, and currency correctly for every user with SvGrid's built-in formatters - without breaking sort and filter.
• Bulk Operations on Selected Rows in SvGrid - Turn row selection into action - bulk edit, delete, archive, and export selected rows in a Svelte data grid with a contextual toolbar.
• Set Filters and Custom Filter Logic in SvGrid - Build Excel-style set filters with checkboxes, custom operators, and faceted filtering in a Svelte data grid.
