Mapper function not applied to dynamically shown columns

Hi @aturiot! It look's like Everett's fix for this issue may also work here. It's a bit hacky since the Column mapper would be the same if the switch value is true or false.

Engineering has been looking into this bug, as they are working on a lot of new table updates. I believe this will be fixed in the next stable release :crossed_fingers: I hope this workaround helps for the time being:
