This started as small thing to bring the Mathcell plugin up to date to allow the use of wikitexet within the system. So with the help co-pilot and many AI hallucinations later ( don’t look at the code too closely!) here it is:
I have expanded this quite a lot!
There is spreadsheet like behaviour using fields as cells. Calulations can be performed using Tiddly formula, or any other wikitext you care to stick in there.
There is an inline version to place cells in text.
There is a nice editing interface.
There is jsx graph integration with, currently two graph types. Also with a nice editing interface.
There is inline KaTeX calculation to allow mixed katex and the results of calculations to be presented seamlessly in rendered KaTeX.
Basic calculations can be done using KaTeX mark up.
I’m quite pleased with this!
