Yusran - please clarify what you mean by show up the specific data. Are you trying to highlight a certain row?

@Yusran Said: Then the code you have posted is fine. Load the data and display the contents of the field myCellArray as Data property of the uitable. I still do not see a problem here. Do you get an error message? Do you want to do something else? I do not know what "but cant show" means.

i got error message when push the button, Error using table (line 281) Invalid parameter name: pushbutton1_Callback.
Error in @(hObject,eventdata)table('pushbutton1_Callback',hObject,eventdata,guidata(hObject))
Caused by: You may have intended to create a table with one row from one or more variables that are character strings. Consider using cell arrays of strings rather than character arrays. Alternatively, create a cell array with one row, and convert that to a table using CELL2TABLE.

Do not name your gui "table": you are confusing MATLAB, which thinks table() is for creating table objects https://www.mathworks.com/help/matlab/ref/table.html which are not related to the display tables, uitable()

oh, ok my fault, thanks for answer, but still erorr
Reference to non-existent field 'myCellArray'.
Error in contoh>pushbutton1_Callback (line 84)
set(handles.uitable1,'Data',myData.myCellArray);
Error in gui_mainfcn (line 95)
feval(varargin{:});
Error in contoh (line 42)
gui_mainfcn(gui_State, varargin{:});
Error in @(hObject,eventdata)contoh('pushbutton1_Callback',hObject,eventdata,guidata(hObject))
Error while evaluating UIControl Callback
what should i do?

At the command line command
dbstop if error
and run your program. When it stops with the error, look at
fieldnames(myData)
whos -file dataplat.mat
I suspect your dataplat.mat does not contain a variable named "myCellArray".
