For the specific of the circumstances, I understand you but also, I need to mention that the official language that we use is English.
Unfortunately, there is no built-in functionality for this.
I would like to suggest you use the jqxGrid with selectionmode property set to singlecell option.
It is possible to be achieved as a workaround.
You could use the cellsRenderer callback (also the cellclassname callback) and depends on the clicked cell to add a specific style there.
This topic will be helpful in this case, too.
Thank you for your understanding.
