Dear developers,
how can I add background color + border dynamically to keep together please? I prepared demo available at
https://jsfiddle.net/janzitniak/h6oac8pb/7/
please select any cell then click to to button Add background color and to the same cell use Add border button. It keeps only last formatting but I would like to keep both of them (background color and bordering as well).
Regards,
Jan
