Styles and dropdowns are gone - php

Question

Using PHPSpreadsheet, when populating an existing spreadsheet, all styles, conditional formatting, dropdowns, etc. are gone.
How can I retain the original settings while writing to php://output?
Here's a screenshot of what the base ODS file should look like:
When opening this template and writing values from the database to the R/A/S/C/I cells, the outcome is this:
Here is the code I have so far. You can ignore $modulePath etc. as that is just the lookup of the full system path to the file.
$original = $modulePath . '/resources/ISO27k-RASCI-tool.ods';
$reader = IOFactory::createReader('Ods');
$sheet = $reader->load($original);
$sheet->setActiveSheetIndex(1);
$sheet->setHasMacros(true);
$col = range('A', 'Z');
$teams = $this->dataRecord->Annex()->Teams();
foreach ($teams as $i => $team) {
$sheet->getActiveSheet()->setCellValue($col[$i + 2] . '1', $team->Name);
}
$writer = new Ods($sheet);
$writer->save('php://output');

Answer 1

Be aware of that not all excel/ods styling commands are implemented in phpspreedsheet.
As well there is no "pivottable" and "format as table" support.
Your table looks like you use at least "format as table".
The problem is that you crate a new file and your file is only a kind of template. Unsupported cell styling will be skipped. The only solution is that you must style your output with the styling commands.
