I'm trying to figure out how to create a BTable with a given size with a stickyHeader.
In BV 2 that was pretty convenient as setting the property as follows worked well:
:sticky-header="availableTableHeight",
where availableTableHeight was in my case a computed property giving values such as "381px".

In the documentation of this project it seems that the aforementioned property is also available, only as a booleanish value.

If I use that property now: sticky-header (i.e. implicitely set as true): I can't observe any effect, why?
Even if I observed an effect, how could I set a given length? If set a certain length on that element or a parent element (such as a div), the table is just as long as the data.

Thanks a lot in advance.
