Hi,
Is there a better way to create the table below (Its a new table consist of id number and cell array data)?
Thanks.
cData=[;];
for i = 1 : length(cellarray)
objectNumber=i;
currentObject=cellarray{i};
newDataRow = {objectNumber, currentObject};
cData=[cData;newDataRow];
disp(cData);
end

Yes
dataId = num2cell( 1:numel( cellarray )).' ;
cData = [dataId, cellarray] ;

Thanks. Wow, great...
And if I wish to add also a text field in your code?.
This would be my code.
newDataRow = {objectNumber, currentObject,'text'};

I am using square brackets actually, which concatenate cell arrays dataId and cellarray. If you had another cell array with whatever content that you wanted to concatenate, you could do the same, e.g.
cData = [dataId, cellarray, labels] ;
but labels would have to have the same number of rows as cellarray (which is mandatory for horizontal concatenation). If you wanted to have only the first cell defined with some text content, you would still have to do something like
labels = cell( size( cellarray )) ;
labels{1} = 'Some text' ;
cData = [dataId, cellarray, labels] ;
