Introduction

μTable is a fast interface for viewing CSV files. It draws much inspiration from thoughtspile/hippotable, but makes different tech choices with the goal of being smaller and faster.

	μTable	Hippotable
JS Framework	ivi	SolidJS
CSV Parsing	μDSV	Arquero (d3-dsv)
Virtualization	own (< 0.5 KB)	TanStack/table (~60 KB)
Sorting / filtering	own + μExpr (< 4 KB)	Arquero (~400 KB)
localStorage Persistence	no	yes
Bundle size	20 KB	416 KB

Both projects are very early, and the choices made by Hippotable are totally sensible, considering its plans to leverage much more of the Arquero library. I have, however, previously tested some Arquero functions (such as grouping) and found its performance to be lacking in multiple areas.

uTable has similar goals as Hippotable, but [perhaps] with greater scrutiny on external dependencies, and will always roll its own solutions when there are significant performance and/or size benefits.
