Converting nested "summary" structure to table

Hello,

I'm trying to convert a nested structure (full of table summaries) back into a table.

filled with

I have tried using Nested2tables but I don't think it will work given the single the nested structure.

Is there any way to create a table of the summary data while keeping the fieldnames from BOTH structures?

Thank you!

So, are you expecting a table like this?

table_name              size    Type        ...
Days_from_development   [118,1] 'double'    ...
HIV                     [52,3]  'string'    ...

Here's the loop version. There may be another way, but I didn't have any luck fighting with Matlab's tricky multiple-cell return behaviour

% create minimal test structure
mystruct.Days_from_development = struct('size',[118,1],'Type','double');
mystruct.HIV = struct('size',[52,3],'Type','string');
% get a list of all the fieldnames (i.e. substructures, i.e. names of tables)
table_names = fieldnames(mystruct);
% loop over substructures
for ind=1:length(table_names)
    % get the string for each substructure's name
    tmp = table_names{ind};
    % dump the substructure to a table row
    % by turning it into a 1xN cell array and putting the substructure string as the first cell
    mytable(ind,:) = cell2table([{tmp} struct2cell(mystruct.(tmp))']);
end
% rename the table variables appropriately
mytable.Properties.VariableNames = [{'table_name'};fieldnames(mystruct.(tmp))]

(this method is not particularly stable. If you have fields that are not all matching substructures, it will error)

Unfortunatley I do have feilds that don't match. But this works well for everything else. Thank you!
