Tabsheet equal tabs

Hi guys.

I have a tabsheet which is 100% width and height and has two tabs, which I want to be the same width, but not sizefull, I mean ValoTheme.TABSHEET_EQUAL_WIDTH is not my case. How it can be implemented? I’ve tried different css variants like simple style=“width: 150px” to each of dom-element for tab, but it doesn’t work. Is there any wirkaround for this or maybe I’ve missed smth.

Thanks in advance.
