Missing tab head in multiple sheets

[gaglioffo]

Hi,
when I create multiple sheet I lose the first "tab field" line. It missing because processingFirstRow become false after the first loop.

Example of code

$this->writer
           ->addNewSheetAndMakeItCurrent()
           ->setName('New Sheet');
...
$this->stream->addRow($table);

Probably an easy approach it's to edit the following function

public function setHeaderStyle($style) 
{
        $this->headerStyle = $style;

        **$this->processingFirstRow = true;**

        return $this;
}

and the new code become

$this->writer
            ->addNewSheetAndMakeItCurrent()
            ->setName('New Sheet');

**$this->stream->setHeaderStyle($stile);** // <- force to set old or new head style
...
$this->stream->addRow($table);

Does anyone have a different approach or a smart solution to suggest?

Thanks a lot
