Modify cell value of a row based on other cell value in same row uitable

2 views (last 30 days)
function uitable4_CellEditCallback(hObject, eventdata, handles)
a = cell2table(a);
a.a6 = (10 / a.a5)*1^4; %where a.a6 is the column to be auto modify after editing column a.a5
a = table2cell(a);
set(handles.uitable4, 'Data',a);
Practically, I want every time I modify the value in a cell from a.a5 column, the a.a6 to be modified automaticaly, for the first row it's working but when I add another row i get the error:
To assign to or create a variable in a table, the number of rows must match the height of the table.
Practically, I unerstand the error but how to make the code working for every row? Thanks!

if colnum == 5;
hObject.Data{rownum,6}=hObject.Data{rownum,colnum}+1000; % Add 1000 to the new value
that resolve the problem
Thanks @Simon Chan for your patience, and answers !

Just move the last comment as an answer.
function uitable4_CellEditCallback(hObject, eventdata, handles)
% Get the row number of your edited cell
rownum = eventdata.Indices(1);
colnum = eventdata.Indices(2);
% Update column 6 when column 5 has a new value
if isequal(colnum,5)
hObject.Data(rownum,6)=hObject.Data(rownum,colnum)+1000; % Add 1000 to the new value
Please accept the answer if it is useful for you.
