shrinkToFit was not handled in StyleMerger so it was overwritten by the default cell style
StyleManager didn't add the property to the xml if shrinkToFit was used without alignment or text wrap.
Unit test
Added support for
mergeCells:
// mergeCells (B2:G2), you may use CellHelper::getColumnLettersFromColumnIndex() to convert from "B2" to "[1,2]"
$writer->mergeCells([1,2], [6, 2]);
cell height:
$row->setHeight(30);
shouldShrinkToFit:
$style->setShouldShrinkToFit();
These changes are implemented for XLSX as that's what I need and test spout on.
This PR adds support for cell alignment for XLSX and ODS files.
You can now align the content of the cells this way:
```
use Box\Spout\Common\Entity\Style\CellAlignment;
use Box\Spout\Writer\Common\Creator\Style\StyleBuilder;
$style = (new StyleBuilder())
->setCellAlignment(CellAlignment::RIGHT)
->build();
...
```
Possible cell alignments are: LEFT, RIGHT, CENTER and JUSTIFY.
