Abstract
The present disclosure relates to implementing changes to a data structure, such as a formula, in a collaborative context. In certain embodiments, collaborative changes made to a formula containing references to other portions of a table are retained or account for when an undo operation is performed. In one aspect, unique identifiers are used to identify and track table features, such as columns, rows, or cells, which may be moved, deleted, or created during a collaborative session. In some instances, collaborative changes may be logged for later application or applied to commands in an undo stack to prevent loss of changes.
