Support for DateTime when writing XLSX

[stof]

The XLSX writer (and maybe also ODS, I haven't check) is missing support for date cells.

There is an inconsistency in the code I think.
In Box\Spout\Writer\XLSX\Manager\WorksheetManager::getCellXml and Box\Spout\Writer\ODS\Manager\WorksheetManager::getCellXml, the case elseif ($cell->isDate()) is not implemented, though Box\Spout\Common\Entity\Cell supports it.
Also, when exporting to CSV, Cell::__toString() tries to cast a DateTime to a string, which is not possible and produces an exception.

#735 adds this to ODT.

PR #751 adds XLSX.

This is true. Cell could support DateTime objects but full support is not ready, hence the error.

Hi, I recently faced this issue of missing support for dates for XLSX in my project. I saw that there were some PRs for this. I think the nicest one was #816. For me this solution is great and it's according to specification. The fact that some clients (Google Docs was mentioned) don't support it doesn't bother me. This shouln't be the reason for not merging this functionality. It works in Excel, is according to spec and it doesn't break anything.

@adrilo Would it be possible to reconsider merge of this PR? Thanks.

Solved in openspout/openspout#13

@Slamdunk Thanks! Any idea when this will be released?

[Slamdunk]

Released now in v3.6.0

Be aware that you need to specify the number format to have the output you need.

[mcorteel-harel]

@Slamdunk Could you give an example? Would that work (seems weird)?

$style = (new StyleBuilder())
    ->setFormat('0.000')
    ->build();
$cell = WriterEntityFactory::createCell(new \DateTime(), $style);

EDIT: Missing build() method

[Slamdunk]

$style = (new StyleBuilder())
    ->setFormat('yyyy-mm-dd');
$cell = WriterEntityFactory::createCell(new \DateTime(), $style);
