How to write a vector in uitable?

I have this columns names on the Matlab UITable

app.UITable.ColumnName = {'Iteracion'; 'Xl'; 'Xu'; 'Xr'; 'f(Xl)'; 'f(Xr)'; 'f(Xl)*f(Xr)'; 'Ea'};

I create a program to write my function answer in Excel

title = [{'i'}, 'xl', 'f(xl)', 'xu', 'f(xu)', 'xr' ,'f(xr)' ,'Ea' ];
xlswrite('DatosBiseccion1.xlsx',title,'Hoja1','A1');
cell = cell+1;    
cell1 = [iter, xl, f(xl), xu , f(xu) , xr, f(xr), Ea];
xlswrite('Biseccion.xlsx',cell1,'Hoja1',strcat('A',int2str(cell)));

Is there any option to modify this code to be used on a Matlab app UITable?

Are you using App Designer or GUIDE, or just creating your GUI manually?

cell is a built in function name, so don't use it as a variable name like you are.

Not sure what you want to do. Do you want to have column headers be the strings you listed but it's not happening either in your GUI or in your Excel workbook? Please clarify. Or do you want to load the cell1 variable into your uitable on your gui like

app.UITable.data = cell1;

I’m using App Designer. The first line are the columns name that I use in the UITable. I use the second code to export an iterative numerical method to excel. I create a vector Called cell1 to store the solutions from the method, and cell+1 to move down the vector on excel lines. What I need to do is match the vector cell1 positions with the UITable same positions and name.
