A method for facilitating private drafting, the method comprising:

• displaying, on a computing device of a first user, a document including a table comprising a plurality of cells, wherein at least one of the cells is governed by a formula and wherein the first user is one of a plurality of users collaborating on the document;
• maintaining an interval-based dependency graph comprising a plurality of nodes, such that each node of the graph represents a range of locations on the table on which at least one formula depends;
• receiving, from the first user, a request to edit the table in a draft mode;
• in response to the edit request, creating a copy of at least a portion of the dependency graph to manage editing instructions in the draft mode;
• receiving, from the first user, an edit for the table in the draft mode;
• displaying a result of the edit on the computing device of the first user but not on computing devices of other users of the plurality of users;
• storing, in an additional node of the copy of the portion of the dependency graph, an editing instruction that represents the edit by the first user;
• receiving, from the first user, a request to publish the edit;
• and
• in response to the request to publish the edit,
• merging the copy of the portion of the dependency graph with the dependency graph, and
• displaying the result of the edit on the computing devices of the other users of the plurality of users.
