improvement(tree): Update table row insertion/removal constraints to only specify columns with intersecting cells.

[Josmithr]

Update insertRows and removeRows to only specify columns for which there are existing cells as constraints.

For sparse tables, this is a pretty big win in terms of both constraint performance and usability.

Note that setCell and removeCell also have corresponding column "nodeInDocument" constraints, so the code is still robust to cell-level changes.
