quadratic VS ag-Grid

https://github.com/quadratichq/quadratic/issues

Hey guys, as the title says I am looking for some suggestions on useful free spreadsheet libraries, similar to excel or google sheets. I saw quadratic (https://github.com/quadratichq/quadratic), which looks really interesting but is in very early alpha, to the point I cant even embed it in my own project yet.

I am glad they started brainstorming how to implement my suggestions for named cells and named ranges [1]. Having complex spreadsheets than span through infinite will be unmaintainable relying only on coordinates

Yes the bundle is huge, we have made no effort yet to optimize it. Feel free to create a PR :)

Here is how we manage cell dependencies https://github.com/quadratichq/quadratic/blob/main/src/grid/...

In this post I’ll show you how, using the AG Grid component and Ably Spaces, you can create a React application that allows users to see not only who else is currently viewing the grid, but using a Flowbite Avatar Stack component, what row each user currently has selected.

something like ag-grid? https://github.com/ag-grid/ag-grid

I personally use https://www.ag-grid.com/ for all my data grid needs. It has a free community version (that should get you covered imo) as well as a paid one with advanced features.

To be fair, in any GUI toolkit, the "table" is abolutely the most complex general purpose widget. People really under estimate the difficult of an efficient implementation. Qt spents YEARS improving their QTableWidget class. The implementation is mind-bogglingly complex. I am sure many very smart summer interns (PhDs!) have tried to tweak that class to squeeze every bit of performance possible. The table class in GTK+ and MSFT DotNet's WPF are equally, freakishly insane.

Consider this idea: Most people who use a table class in a GUI framework assume it is essentially infinitely scalable (myself included!). I am talking about millions of rows or thousands of columns with all kinds of silly widgets injected into individual cells. It is a crazy hard computer science problem to solve. I would not doubt there are many PhD thesises written on the topic of fast, scalable table widgets.

Beyond desktop GUI toolkits, people have tried to do the same in a browser (HTML/CSS/JS). Have you seen AG-Grid? Woah, it is unbelievable how much goddamn data you can squeeze into that widget. Most Wall Streets web-based trading apps use it one way or another. It's just so hard to beat. Ref: https://www.ag-grid.com/ There must be 1,000 person years of optimisation sunk into that implementation.
