Hello, Libor!
 
Thank you for reaching out to us.
 
Kindly note that a lot of things have changed during these 6 years. Regarding the mentioned feature, we haven't restored the fitGridLines property.
However, now it is possible to hide the borders for empty cells using the following CSS styles:

.fm-empty {   
    border-right: none !important;  
    border-bottom: none !important; 
}

We have prepared a JSFIddle example for visualization: https://jsfiddle.net/flexmonster/vd0ohf8x/.
 
Could you please let us know if the suggested approach works well for your case?
 
Kind regards,
Solomiia
