--- Comment #72 from Emily Mabrey <emilymabrey93 at gmail.com> ---
Is making a truly dynamic sheet even needed? Excel only allows a static number
of columns and a static number of rows and it seems like a massive undertaking
for such a seemingly niche application. Excel 2016/ M365 supports 1,048,576
rows or 16,384 columns as that static limit.

Looking over the comments I can see that there may have already been an effort
to produce a dynamically sized sheet. Has anyone done testing to see if the
dynamic sheet comes with any performance penalty? If so it might be wise to use
a large static value under most cases and allow the dynamic sizing as a niche
option with an opt-in configuration. That would prevent constant
allocation/frees around when adding and removing rows and cols if that does
turn out to be a performance problem.

I would look into the performance consequences myself, but I am brand-new to
this project and wholly unfamiliar with the code base and procedures for
performance monitoring of this project. If anyone could point me to some
guiding documentations I would be willing to make an effort at fulfilling my
own request.
