Hello everybody,
it might seems easy to some of you but I'm struggling to import a .txt or a .csv - file into a single cell of a table in Matlab.
I've read all the sites like load variables or import data and other stuff.
for a better understanding i attached a picture of my created table.
The task i want to realize is that if click on a cell (each cell of the column should be able to do this) in the column of 'transient', I want a window to pop up, so I can select a .txt-file (contains a number for Power and a number for the time)
Is this even possible?
I'm hoping for some help :)
if you need my code for the table as well, tell me

You can use CellSelectionCallback and uigetfile to load data from a file.

Thank you for your answer !
I'm already trying something
do you think this code would help me
my actual main code:
% --- FIGURE -------------------------------------
handles.figure1 = figure( ...
'Tag', 'figure1', ...
'Units', 'characters', ...
'Position', [102.8 24.2307692307692 126.8 33], ...
'Name', 'Parameter', ...
'MenuBar', 'figure', ...
'NumberTitle', 'off', ...
'Color', [0.941 0.941 0.941]);
% --- UITABLE -------------------------------------
% Initialize empty string for components of the Data
Data{i} = '';
for i = 1:numel(Data)
handles.uitable1 = uitable( ...
'Parent', handles.figure1, ...
'Tag', 'uitable1', ...
'UserData', zeros(1,0), ...
'Units', 'characters', ...
'Position', [12.2 8 85.6 21], ...
'BackgroundColor', [1 1 1;0.961 0.961 0.961], ...
'ColumnEditable', [true,true,true,true,true], ...
'ColumnFormat', {'char','char','char','char','char'}, ...
'ColumnName',{'ID','<html>P<sub>i</sub> -stationary<br>[W]','<html>P<sub>i</sub> -transient<br>[W/t]','<html>&Omega','V'}, ... % '<html>P<sub>i</sup></html>[W]'für griechische Buchstaben in einer Column <HTML>&Buchstabe
'ColumnWidth', {'auto','auto','auto','auto','auto'}, ...
'Data',Data); % add the "string" Data
and after this then the cellselectioncallback ?
would consider something like this:
function data_uitable1_CellSelectionCallback(hObject, eventdata, handles)
% hObject handle to data_uitable (see GCBO)
% eventdata structure with the following fields (see MATLAB.UI.CONTROL.TABLE)
% Indices: row and column indices of the cell(s) currently selecteds
% handles structure with handles and user data (see GUIDATA)
% disp(eventdata)
handles.datatable_row = eventdata.Indices(1);
handles.datatable_col = eventdata.Indices(2);
guidata(hObject, handles);
This is something I found on the internet is this appropriate for me or not? What do I have to change?

function uitable1_CellEditCallback(hObject, eventdata, handles)
Columndata = get(hObject,'Data');
[FileName,PathName] = uigetfile({'*.txt'; '*.csv'},'Select the configuration');
if strcmp(Columndata(1,1),'User Defined')
FilePath = fullfile(PathName,FileName);
if isequal(FileName,0)
[pathstr, name, ext] = fileparts(FilePath);
ParameterList{end+1} = name;
This is some other code I tried... but I don't have a clue how to import my file into a cell of my column now -.-
I'm pretty frustrated with this right now .....
