Abstract: Systems and methods disclosed herein provide a method of managing a state of a virtual rendering surface for an electronic document. The method includes obtaining, at a user device from a remote storage server, content relating to an electronic document, and rendering the content of the electronic document onto a first virtual rendering surface. The method further includes maintaining a second virtual rendering surface that stores a current state of the first virtual rendering surface. The method further includes obtaining an operation command relating to the electronic document, and retrieving first state information of the first virtual rendering surface and second state information of the second virtual rendering surface. The method further includes applying the operation command to the rendered content of the electronic document on the first virtual rendering surface, and updating at least one of the first state information or the second state information based on a type of the operation command.

Abstract: Systems and methods are disclosed herein for resolving a change to a table. A processing circuitry receives, from a user in a collaborative document editing environment, the change to the table, wherein the change comprises an expansion of a first cell in the table. A first state of the first cell is identified, wherein the state is indicative of a number of columns and a number of rows over which the first cell spans, and at least one of the number of columns and the number of rows is greater than one. A second state of a second cell that is adjacent to the first cell is identified, and the processing circuitry selects whether to allow the expansion of the first cell based on the second state of the second cell.

Abstract: Systems and methods may include updating subsets of elements of electronic documents. Associations of types of mutations, mutation locations, and subsets to update are stored in a database. A mutation to the element is received, and a type and location of the mutation are determined. Based on a stored association, a subset of the element is determined. The determined subset is associated with the determined type and determined location. The element is updated by updating the subset, and the updated element is displayed on a user device.
