List support in table cells

We often need to share a short list of info in a tabular format, but our tables don't support lists.

gh gets around this by allowing for html lists inside of markdown tables (ugly but functional)

we currently work around it using - and <br> but this is not ideal because list items don't wrap properly / use non-standard bullets

1. @colleenmcginnis to create list of high-risk tables
2. Writers fix tables with existing syntax
3. Figure out what actual requirements are
4. Build complex table support (potentially as horizontal def list?)
