1. A computer-implemented data processing system, comprising: a table comprising rows, and columns that indicate an identifier, name, outline level, view position, data position, and descendant count, the table in part defines a hierarchical dataset of an entire recordset; a position converter index comprising an ordered index of the rows used to track an expanded/collapsed state of the table and to translate between a view position and a data position of the hierarchical dataset; a collapsed set list comprising a list of collapsed rows, configured to indicate whether a respective row of the hierarchical dataset is to be collapsed or expanded; a paging component configured to page the table, the position converter, and the set list to obtain relevant rows to a row operation on one or more rows of a client viewset, thereby reducing an amount of processed data to the relevant rows, wherein paging comprises obtaining a subset of rows through viewing operations including sorting, filtering, or grouping, and wherein the client viewset represents what a user can physically see on a client at a given moment; an update component configured to update the client viewset to include the relevant rows in response to a row change operation comprising a row operation of an editing nature, the update to the client viewset based on row keys associated with the paged table; and a processor that executes computer-executable instructions associated with at least one of the table, the position converter index, the collapsed set list, the paging component, or the update component.
