This driver supports the following operation modes:
|Direct Rendering||not really, see below|
This driver accepts the following options:
|bodyFormat||mixed||The format for body cells (either 0 [= "no format"] or a Spreadsheet_Excel_Writer_Format object) Please see the NOTE ABOUT FORMATTING below.||0|
|border||int||Border drawn around the whole datagrid: 0 => none, 1 => thin, 2 => thick (NOT IMPLEMENTED YET)||0|
|buildFooter||bool||Whether to build the footer.||true|
|buildHeader||bool||Whether to build the header.||true|
|defaultCellValue||string||What value to put by default into empty cells.||null|
|defaultColumnValues||array||Per-column default cell value. This is an array of the form: array(fieldName => value, ...).||array()|
|encoding||string||The content encoding. If the mbstring extension is present the default value is set from mb_internal_encoding(), otherwise it is ISO-8859-1.||'ISO-8859-1'|
|excludeVars||array||Variables to be removed from the generated HTTP queries.||array()|
|extraVars||array||Variables to be added to the generated HTTP queries.||array()|
|filename||string||The filename of the spreadsheet||'spreadsheet.xls'|
|fillWithEmptyRows||bool||Ensures that all pages have the same number of rows.||false|
|headerBorder||int||Border between the header and body: 0 => none, 1 => thin, 2 => thick (NOT IMPLEMENTED YET)||0|
|headerFormat||mixed||The format for header cells (either 0 [= "no format"] or a Spreadsheet_Excel_Writer_Format object) Please see the NOTE ABOUT FORMATTING below.||0|
|hideColumnLinks||array||By default sorting links are enabled on all columns. With this option it is possible to disable sorting links on specific columns. This is an array of the form: array(fieldName, ...). This option only affects drivers that support sorting.||array()|
|numberAlign||bool||Whether to right-align numeric values.||true|
|sendToBrowser||bool||Should the spreadsheet be send to the browser? (true = send to browser, false = write to a file)||true|
|startCol||int||The Worksheet column number to start rendering at||0|
|startRow||int||The Worksheet row number to start rendering at||0|
|tempDir||string||A temporary directory to be used by Spreadsheet_Excel_Writer (cp. "General Notes" section).||null|
|version||int||If you don't pass a worksheet object to this renderer, you can set the BIFF version with this option. The only accepted value by Spreadsheet_Excel_Writer is 8 (for usage of the BIFF8 format). All other values will lead to the older format (which is needed if you get errors in Excel, e.g. about a broken file).||8|
|worksheet||object||Optional reference to a Spreadsheet_Excel_Writer_Worksheet object. You can leave this to null except if your workbook contains several worksheets and you want to fill a specific one.||null|
This driver does not support the flatten() method. You can not retrieve its output with DataGrid::getOutput(). You can either render it directly to the browser or save it to a file. See the "sendToBrowser" and "filename" options.
This driver has container support. You can use Structures_DataGrid::fill() with it; that's even recommended.
If PHP's safe_mode is enabled, Spreadsheet_Excel_Writer sometimes fails to generate the Excel file. You can avoid this problem by setting the 'tempDir' option to a (temporary) directory that is writable by PHP.
NOTE ABOUT FORMATTING:
You can specify some formatting with the 'headerFormat' and 'bodyFormat' options, or with setBodyFormat() and setHeaderFormat().
But beware of the following from the Spreadsheet_Excel_Writer manual: "Formats can't be created directly by a new call. You have to create a format using the addFormat() method from a Workbook, which associates your Format with this Workbook (you can't use the Format with another Workbook)."
What this means is that if you want to pass a format to this driver you have to "derive" the Format object out of the workbook used in the driver.
The easiest way to do this is:
// Create a workbook $workbook = new Spreadsheet_Excel_Writer(); // Specify that spreadsheet must be sent the browser $workbook->send('test.xls'); // Create your format $format_bold =& $workbook->addFormat(); $format_bold->setBold(); // Fill the workbook, passing the format as an option $options = array('headerFormat' => &$format_bold); $datagrid->fill($workbook, $options);
