Hi Sven Kannenberg,
Thank you for your purchase.

Can you please tell me did you try to use our conditional formatting. 
You can take a look at our documentation about conditional formating so I hope you can find some useful hints.
Let me know the result.

Best regards. 

Hi Sven,

Unfortunately this functionality is not available without some customization.
If you are interested please give us detailed instructions and we can send you quote for this service.
I can give you some guide how it should be done so maybe you can implement it by yourself.
If you are skillful with JS you can use hooks to alter table content on php side. 
Take a look at your documentation for developers about -filters and hooks so maybe you can find something useful.

Hi Sven

I can suggest you to take a look at this hook

wpdatatables_after_table( $table_id )
This action is called after the table is rendered on the page. $table_id is the table ID from wp_wpdatatables table.

Also please note that customization questions like this one are not covered in the included support for the plugin. Included support covers help with bugs and general inquiries for the plugin features, but not writing custom code.
It would not be fair to other customers that have similar requests to write a code here.
As you're developing some custom solution if you need our assistance we can offer you our paid customization service.

Thank you for understanding.
Best regards.

Hi Sven,

Glad that you found the solution and implement the function, good job.
We are very happy to hear that you are satisfied with our product.
