Thanks for the quick reply, Justin!
The table component has built in filtering functionality that’s just client side filters, so your query won’t re-run
I tried looking for this, but didn't find anything else besides the filter icon in the bottom right of the table UI, which can't handle our needs (e.g. games column has 1+ overlap with games multiselect). It'd be awesome to handle built-in JS filtering functionality! Is there another way to setup a JS filter, e.g. in the settings? If so, can you share how to use it?
The reason you’re getting that error is that in Run JS Code queries, you don’t need to use
{{ }}
I see, thanks! If it's not too hard, might make sense for you to provide a better error message in that case 
Transformers aren’t queries, so they don’t “trigger” - you just reference the
.valueproperty!
I'm not sure I understand what you're saying, but I guess I should use a Run JS Code query here instead.
