Aggregation

4 articles on aggregation in a Svelte 5 data grid: practical guides with copy-paste code, from the team building SvGrid.

• Aggregation Functions Explained (Sum, Avg, Min, Max, Count) - A practical look at SvGrid's five built-in aggregations - what they compute, where the math quietly breaks, and how to handle the server-paged case where client totals are meaningless.
• Grouping and Aggregation in a Svelte Data Grid - How to group rows by one or more columns and show per-group sums, averages, and counts using SvGrid's columnGroupingFeature - with real code and the edge cases that actually bite.
• A Sticky Summary / Footer Row in SvGrid - Pin aggregate totals at the bottom of your grid so they stay visible while rows scroll - column footers that recalculate live when filters change.
• Pivot Tables in Svelte - Summarize Data Without a Spreadsheet - Run a cross-tab pivot directly inside your Svelte app using @svgrid/enterprise createPivotModel - no Excel, no server-side aggregation, no stale exports.
