[development] Table hook idea

Is there any interest in adding hook support to table rows and cells to allow on-the-fly modification of table data by modules? Something like "table_alter($headers, $rows)" and/or "row_alter" and "cell_alter". Seems to me this would be easy to do by adding support for an "id" key for tables, rows, and/or cells so if the id is set the hook is invoked in other modules. Cheers, Mike
