Hy, i'm trying to reset the uitable of my GUI but its not working, I used:
set(handles.uitable,'Data','');
It apparently clean the data, but it also doesnt allow me to edit the uitable anymore. I had also used the function "reset":
reset(handles.uitable), But it didnt work either.

newd = get(handles.uitable,'Data');
charlocs = cellfun(@ischar, newd);
newd(charlocs) = {''};
newd(~charlocs) = {[]};
set(handles.uitable, 'Data', newd);

hi Walter, i have same problem. but now it has been solved with your code. May i ask what the meaning of @ischar ? newd(charlocs) = {''}; ? newd(~charlocs) = {[]}; ? thank you

uitable 'data' property takes a cell array, each element of which can be a string or numeric. The cellfun(@ischar, newd) runs through each cell entry and tests to see if it is string or not, returning true if it is and false otherwise. The result, charlocs, is the same size as the cell array but is true for the places that were strings and false otherwise. This logical mask is then used to set those places that were strings to be empty strings, and the negation of the logical mask is used to set the other locations to empty arrays. In this way each local is set to the empty version of what it was before, which preserves information about whether the entry was a string or not.

If [] does not work for those, then use 0 for them. 0 means unchecked.

set(handles.checkbox1,0);

Are you asking about uicontrol style checkbox? If so then set their Value property to 0. set(handles.checkbox1, 'Value', 0)
I thought you were asking about uitable checkbox columns.
