Hello
There is a problem with 10 empty rows between every normal row in dynamic table, when data is encoded
But snippet works well with equal data
The problem can be caused by styling. DataTable expects to have some fixed row height, and if this value is changed through styling, it can render invalid rows.
If you need to have a custom row height - use https://docs.webix.com/api__link__ui.treetable_rowheight_config.html
Also, a similar problem can occur if you have non-unique IDs for rows.
