Anyways, until 15-20 years ago I don’t remember chasanim being lifted on a table. It was always and only on a chair that they lifted the choson. The table seems to be a bit modernish.
In fact, the idea of lifting the choson and the kallah at the same time to wave to each other is also nisht oisgehalten. It wasn’t done in ehrliche weddings until not too long ago. And it’s lacking in the tznius department, especially since the chosen and kallah aren’t the only ones who gain visibility across the mechitza when that happens.
