Seems that has no simple solution and can't be recognized as concrete issue of some component..
The problem is - scrollable table has huge script initialization and every inplace component inside also causes script object and initialization appearance.. So if think about right solution - you could probably rise a reqeust in our wiki for new component creation something like inplaceSupport which will be represented by one script object which could be used for multiple outputs.. But it's RFC for sure. This can't be done within current inplaceInputs miplementation.
