Build and export tables using "struct2table" function

Dears,

I would like to build a table in "ascii" format, using the "struct2table" function. When printed into a cell my structure as the following characteristics:

    report.COUNTRY.SOURCE.SCENARIO.CATEGORY.ENTITY = YEAR YEAR

Therefore in order to use the "struct2table" function I wrote a script that loops over field names as follow:

function comboloop = loopover(myStruct)

country=fieldnames(myStruct);
for countryidx=1:length(country)
    countryname=country{countryidx};
    source=fieldnames(myStruct.(countryname))    
    for sourceidx=1:length(source)
        sourcename=source{sourceidx};
        scenario=fieldnames(myStruct.(countryname).(sourcename))        
        for scenarioidx=1:length(scenario)
            scenarioname=scenario{scenarioidx};
            category=fieldnames(myStruct.(countryname).(sourcename).(scenarioname))            
            for categoryidx=1:length(category)
                categoryname=category{categoryidx};
                struct2table(myStruct.(countryname).(sourcename).(scenarioname).(categoryname))
            end
        end
    end
end
end

Then, I have two problem with the output:

• The output is printed directly on the command window, therefore how can I get an output as a table (ascii) in the workspace or outside matlab? When I use:

table=struct2table(myStruct.(countryname).(sourcename).(scenarioname).(categoryname))

I have the error message "too many output arguments".

• How can I append the results of the line 12 as a row header of the created output?

category=fieldnames(myStruct.(countryname).(sourcename).(scenarioname))

Any kind of helps or hints is greatly appreciated since I am struggling quiet a lot for this task! In order to run the code a minimal example of the structure is attached
