Row Heights in Electronic Documents

A computer-implemented method for managing row height in an electronic document includes receiving, at a computing device, a request to display a portion of a document that defines a plurality of rows of content and that is represented by a document model; determining heights of the plurality of rows and saving information about the determined heights in a cache that correlates rows to the height information; and using the document model and the cache to generate a view of the document model having the determined row heights.
