How to use rowspan in kibana table?

Hello there. I'm using "Data Table" visualization in kibana 6.8 with following settings:

It works nice, but I would like to filter and join cells in rows into one, if values are equal.
For example, I have the same value "UNKNOWN_0" in the same cell in few rows. I would like to group rows by this value and join "UNKNOWN_0" cells into one like this:

In html table it is possible to do with "rowspan" attribute

but I don't know how to achieve this in kibana. Is it possible?

I'm afraid that feature is not supported in Kibana Data Tables.
You could try using a markdown visualization or Canvas if your elasticsearch queries aren't too complicated.
