Brad,
Each row of Make is a collection of strings that cannot be concatenated automagically.
You can concatenate the strings yourself using a specified delimiter like this:
Company = {'Company_A' 'Company_B'};
Run_Numbers = {'10000' '2500'};
Make = {{'Ford' 'Audi' 'Chevy'} {'Chevy' 'Volvo'}};
% Create table from workspace variables
Z = table(Company', Run_Numbers', Make', 'VariableNames',{'Company_Name' 'Run_Numbers' 'Make'});
% Reassign Z.Make with concatenated strings
% I'm using a space to separate each string.
% You can use other characters like ',' or ';'
Z.Make = cellfun(@(c)delimcat(c,' '),Z.Make,'UniformOutput',false);
% below is a function to concatenate strings.
% you can paste it as a subfunction into an
% existing function or you can make a file called
% delimcat.m and save it on your path
function c = delimcat(c,d)
c = [c;repmat({d},1,numel(c)-1),{''}];
c = [c{:}];
From here, writetable will output the concatenated Make strings.
Hope this helps.
