> WYSIWYG Exports > --------------- > > Key: DISPL-245 > URL: http://jira.codehaus.org/browse/DISPL-245 > Project: DisplayTag > Issue Type: Improvement > Components: HTML Generation, Export > Affects Versions: 1.1 > Fix For: 1.1 > > Attachments: displaytagExamplePatch.txt, > displaytagExportPoiPatch.txt, displaytagPatch.txt, ico_file_rtf.png > > > Request for enhancements of the export facility > 1. The default exporters should render the table as close as possible > to the rendered HTML. When typical business users are presented with the > displaytag export facility, they usually expect the exported Excel or PDF > to > look just like the HTML in their browser; they expect a WYSIWYG rendering. > 2. The export API should encourage reuse of the table-rendering logic > employed to render the table in a JSP. For instance, to render the > grouping > in my PDF export just as it appears in the HTML, I would have had to > re-implement TableTag.groupColumns(). Also, any future changes to the > table rendering would not be included in my PDF export. So, this looked > like a job for the Template Method pattern, which also applies nicely to > the > decorators, to ensure that the HTML and default export > renderings will be in synch. > 3. Include caption in export. > 4. Include footer in export. > 5. Export in RTF format. > The attached patch implements the above enhancements. > <a > href="http://www.jamesgood.com:8080/displaytag-examples-1.1-SNAPSHOT/example-new-export.jsp";> > Here's a live example and a more detailed explanation.</a> > Following are potential additional export enhacements I'm working on. > 1. Use css table styles as style configuration for Excel, PDF, and RTF > exports. > If not practical, provide export style config properties. > 2. Specify Excel formats for columns, e.g., ##.##. > 3. Include smart linking in Excel, PDF, and RTF exports. > 4. Export just the current page, a page range, or all data, especially if > paging is used. > The ui may look like this: > Export options: Excel | PDF | RTF | From: [1] To: [1] (default to this > page) > Export options: Excel | PDF | RTF | From: [1] To: [max] (default to all) > Defaults to exporting what's on the page currently. Default would be > configurable through property. > 6. Set the column width to the max column string value width. > 7. Exporters should support nested tables. > 8. Implement font styles in RTF export, e.g., bold face. > 9. Export in MS Word format using POI. > Related Jira issues: > <ol> > <li>http://jira.codehaus.org/browse/DISPL-194 > <li>http://jira.codehaus.org/browse/DISPL-123 > </ol> > Unit Tests: > The main code change this patch supplies is a refactoring of the > table-rendering > code. As such, the relevant unit test are the existing tests, > <a > href="http://www.jamesgood.com:8080/displaytag-examples-1.1-SNAPSHOT/docs/multiproject/displaytag/junit-report.html";> > all of which succeeded.</a> > -Jorge -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.codehaus.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira ------------------------------------------------------------------------- Take Surveys.
