The Dynamic Columns option in a table is great, and the ability to write code to handle some formatting (label, format, hidden, editable) is great, but it would be really nice to enable the "Appearance" options for dynamic columns as well. Specifically this section:
The dynamic column docs show a use case very similar to my own, where dates are columns. This leads to very wide tables requiring scrolling, but I can't pin a column or highlight a the current date's column, which would be great and make the table much more usable.
