Hi, Tried several solutions found in the forum but none of them worked, in my program, when a cell is selected, all the info of the row is displayed in different edit cases, when the cell in the uitable is edited and enter is pressed, the wanted value changes properly but the CellSelectionCallback is called again and the indices this time are inexistent and returns an error. Any way of fixing this? Thanks in advance

Nice. I posted the rest as an answer so that this question is marked as solved.

Hi - this simples way to do is just to "refresh" the "Data" field;
% Refresh the "Data" field" to its own = Unselect
handles.my_tbl.Data = handles.my_tbl.Data;

Following the comments under the question, we've arrived to the answer.
For some reason, pressing enter after entering data in a UItable activates your cellselectionCallback (which isn't the case when I try it using a simple UI table in 2018a).
When your cellSelectionCallback is activated after pressing enter, the indices are empty.
The real solution would be to prevent the unnecessary callback in the first place but without playing around with your entire GUI I cannot do that remotely.
The alternative solution is to escape from the callback function when the indices are empty.
Insert this at the top of your cellSelectionCallback function.
if isempty(eventdata.Indices)
return
end

function [] = DeselectCellinUItable()
%---------------------------------------------------------------
uif = uifigure();
uif.Units = 'normalized';
uif.Position = [0.10, 0.50, 0.80, 0.40];
%---------------------------------------------------------------
uit = uitable(uif);
uit.Units = 'normalized';
uit.Position = [0.10, 0.50, 0.80, 0.40];
uit.Data = cell2table(num2cell(rand(10,7)));
uit.RowName = 'numbered';
uit.ColumnEditable = true;
uit.SelectionType = 'cell';
uit.Multiselect = 'off';
uit.SelectionChangedFcn = @(src,event) DeselectUItable;
%---------------------------------------------------------------
function DeselectUItable
uit.Selection = [];
end
%---------------------------------------------------------------
end
