Svelte Data Grid Guides and Tutorials

Learn to build with a Svelte data grid: editing, filtering, sorting, grouping, selection, columns, cells, performance, theming, and real-world use cases.

Everything you need to go from a first render to a production grid. These guides cover the core features - editing, filtering, sorting, grouping, selection, columns, and cells - plus performance, theming, and complete real-world screens. Work through them in order or jump to the feature you need.

Core features

Concepts and performance

The ideas behind fast, correct grids.

Avoiding Layout Thrash in Custom Grid Cells - Layout thrash from interleaved DOM reads and writes is the most common cause of scroll jank in grids with custom cells - here is how to find it and design your way out of it.
Client-Side vs Server-Side Data for Tables - The architectural fork that determines your grid's performance ceiling - how to pick the right data mode and wire it correctly in SvGrid.
Column Virtualization Explained - Row virtualization is well understood, but wide grids expose a second bottleneck. Here is how column virtualization works, when you actually need it, and what trade-offs to expect.
Controlled vs Uncontrolled Grid State - Who owns sort, filter, and page state - you or the grid? The answer shapes your whole integration. Here is how to think about it and when each mode pays off.
CSV vs XLSX vs TSV - Which Export Format? - A practical breakdown of CSV, XLSX, and TSV for data grid exports - when each format earns its keep, what each one silently loses, and how to wire all three in SvGrid.
Data Grid vs Data Table - What's the Difference? - The terms overlap, but they point at different capability levels. Here is how to tell them apart and pick the right abstraction before you start building.
Debounce vs Throttle (for Grids and Beyond) - Debounce and throttle are not interchangeable. Here is when each one belongs in your data grid, with real code for filter inputs, live feeds, and scroll.
