You can writetable and then fix the column width with an actxserver
fullFilename = fullfile(pwd,'mysheet.xlsx'); % or whatever name you picked
e = actxserver('Excel.Application'); % open excel
ewb=e.Workbooks;
ef = ewb.Open(fullFilename); % open file
ews = ef.ActiveSheet; % get active sheet
ewsRange = Range(ews,'A1:B1'); % get cell A1 and B1 for example
ewsRange.ColumnWidth = [100 200]; % change the column widths
% save, close, quit, delete!
ef.Save;
ef.Close;
e.Quit;
delete(e);
Here i set it to 100, but change it to what your column width.
OR have a helper function to get the columnwidth before you do the writetable. But i think you have to get each column. so you end up with
function writetableTemplate(...)
getTemplateProps(...)
writetable(...)
setTemplateProps(...) % to fix it
end
