Note, that the document service manager is different from the main service manager used when connecting to the office. The service manager of the spreadsheet document model creates shape objects, text fields for page headers and form controls that can be added to spreadsheets. When working with document data, almost everything happens in the spreadsheet objects extracted from the spreadsheets container. The core of the spreadsheet document model are the spreadsheets contained in the spreadsheets container. The spreadsheet document model in the Apache OpenOffice API has five major architectural areas (see Illustration 9.1) The five areas are: The following table shows the services for cells and cell ranges.
Several services of the spreadsheet application representing cells and cell ranges extend the common services from the module com::sun::star::table. In addition, spreadsheet tables are fully based on the specifications given and are extended by additional specifications from the module. Regarding the compatibility of text and spreadsheet tables, the corresponding features are also located in the module. Basic table features are defined in the module. The implementations of the various tables differ due to each of their specializations. Alternately, spreadsheets support only basic formatting capabilities and text tables perform elementary calculations. Text tables offer full functionality for text formatting, where spreadsheets support complex calculations. Being specialized in such a way means that each concept has its strength. Text tables handle text contents, database tables offer database functionality and spreadsheets operate on data cells that can be evaluated.
Apache OpenOffice API knows three variants of tables: text tables (see Tables), database tables (see Table Service) and spreadsheets.
