"I'm curious what API you would use for implementing a table with varying row heights (that you only know upon rendering but can guess beforehand), sortable columns and millions of rows." In general my policy is that when things get really complicated or specialized, the application knows a lot more about its use case than some trying-to-be-general API does, so it makes sense for the application to do most of the work of dealing with the row heights or whatever. (It's hard for me to answer more concretely since it depends on exactly what is being implemented, which I don't know.)
