My column and row names are not transferring to Excel when I use writetable on App Designer

I cannot get the column or row names to transfer to excel when using writetable on App Designer.

app.UITable3.Data=Temperature ; % Temperature is a combination of table 1 and 2
Names={'CH1','CH2','CH3','CH4','CH5','CH6','CH7','CH8','CH9','CH10','CH11','CH12','CH13','CH14','CH15','CH16','CH17','CH18','CH19','CH20'};
app.UITable3.ColumnName=Names; % this table looks correct on the app

LineNumber = 1 ; % Just an example, edit field defines this
InputFile=('Temperature Table Line %s.xlsx');
filename=sprintf(InputFile,LineNumber);
t=table(app.UITable3.Data); % When I don't use this line and the next is "writematrix(app.UITable3.Data,...) I only get values
writetable(t,filename)

In one case I need column names and on table 4 I need both column and row names to export to Excel. What can I do?

Thank you.

Read the writetable doc --

writetable(t,filename,'writevariablenames',1)

There are many other options available as well, see the examples and use what you need to get the desired result.
