How to split stats command results into rows

[ipoluda]

I have proxy logs, in which I am interested in 4 fields: the ip address of the user's computer, the category of the site he visits and the total amount of incoming and outgoing traffic for each category. Now I got such a table, but I needed it to be like in the second table on the screenshot. I just can't find a solution, I ask the SPL guru to help me)))
My query:
index=proxy 
| stats sum(bytes_in) as totalBytesIn, sum(bytes_out) as totalBytesOut, values(category) by src_host

Is this the sort of thing you are after?

index=proxy 
| stats sum(bytes_in) as totalBytesIn, sum(bytes_out) as totalBytesOut by src_host category
| stats list(totalBytesIn) as totalBytesIn, list(totalBytesOut) as totalBytesOut, list(category) as category by src_host
