I would like to format data from drupal, adding some color in specific cells, from an analysis of the retrieved values.
I test “Views Data Export” module (https://www.drupal.org/project/views_data_export), but from my test :
- “Excel sheet header” rules work
- “Excel conditional formatting” rules do not work
I carefully red answers in the topic How to export Views data in separate sheets/tables to Excel file? and the link for PHPExcel (https://www.drupal.org/project/phpexcel)
I wrote the code,
but I did not understand how the hook can be fired.
I also carefully red the link https://www.drupal.org/node/1351450 , but no more information.
Is there anybody who can give a complete sample?
