No problem, it really is fine. It could be a huge job, or maybe a simple table restructure, but maybe you can offer to collapse years at a time as nesting tables, not sure if this is even possible if you are limited to 32 of them at any given time. I figured this way maybe the years can stay collapsed even if the sub-table stays expanded due to some kind of limitation. I am sure you already thought about these, but it's still perfectly usable.
Also, maybe it's my aging phone, but the website seems to hang for a while before it can be responsive on Chrome on Android 6.0.
