Error using cellstr. Shows error for element that doesn't exist.

I am getting the following error:

Error using cellstr (line 44) Element 154 is not a string scalar or character array. All elements of cell input must be string scalars or character arrays.

But the array I am trying to conver has size: [153 4]

I am trying to display the data to MATLAB Table (App Designer).

I am saving the data into a cell matrix form then converting to string to display in a table in the app.

TblAllInfo=[app.FMain',ChannelNameFinal',LocationFinal',ChannelFilter'];
app.UITableAll.Data=cellstr(TblAllInfo);

I can duplicate the error using this simple example. So the problem is TblAllInfo{1,2}. It is the 154th element. It is not a char array.

a =
  3×2 cell array
    {'a'}    {[1]}
    {'a'}    {[2]}
    {'c'}    {[3]}
>> cellstr(a)
Error using cellstr (line 44)
Element 4 is not a string scalar or character array. All elements of cell input must be string
scalars or character arrays.

Yes, exactly this. How to resolve it ?

[Fangjun Jiang]

The method depends on the data types. Why don't you show some example data?

In my example data, you could use cellstr(string(a))

For now I have added the following code, so that I can proceed with my work. If anyone has any better answers. TIA :)

for i=1:length(TblAllInfo)
        Data1{i}=string(TblAllInfo(i,:));
        Data2{i,:}=cellstr(Data1{1,i});
        Data3(i,:)=Data2{i};
    end
    
    app.UITableAll.Data=Data3;

app.UITableAll.Data=cellstr(TblAllInfo(:,1));
