If you use PaginatedTable on entities pages (VDisk, PDisk, StorageGroup), in most cases you know or at least can assume number of entities. Please pass it to PaginatedTable as initialEntitiesCount

Came up only with the most obvious idea of predicting number of entities

If you meant something different - give me a clue =)

Yes, I meant something like this. For some pages we can be sure, that there would be only 1 row in table, or some value in range

NodePage - many groups (initial count undefined), 1 node
GroupPage - 1 group, usually up to 9 nodes
PDiskPage - up to 24 groups (but usually less, 9-10 initial value looks fine), 1 node
VDiskPage - 1 group, 1 node

And it would be better to implement it with some helper functions:

function getStorageNodesInitialEntitiesCount (viewContext){
  if(valueIsDefined(nodeId)){
    return 1
  }
  // other conditions

  return undefined
}
