Table performance with 100,000 rows #1128

@runrc

Description

@runrc

Describe the feature

I have been experimenting with Cogent Core for our needs and have encountered possible performance issues which would be useful if addressed. Our requirements deal with large amounts of data.

For example, create a table with two fields and 100,000 rows and scroll the table, the redraw is laggy. Now, I know 100,000 rows is a lot, but just wondering, as the API stabilises - is now is the time to address and improve performance across all widgets?

An interim solution is to filter the data before adding to the table which is probably what we'll do, but I was interested in the thoughts of the team regarding profiling and improving performance and whether this is planned?
