Additional totals in tables

[lshnls]

To account for the allocation of resources for various projects, we assign tags to virtual machines.
Each tag is a project. When I do a tag search in order to find all the project resources, I want to calculate the total allocation of CPU, Memory, HDD.
It would be convenient if the sum of the rows was indicated in the header of each table for all rows with numeric parameters. For example, in parentheses after the column name.
