how to use categorical in uitable

hi, I want to choose as value in a table field 'Fil' or 'Stat'

cat=categorical({'Fil';'Stat'});
name={'A','B'};
nrows=numel(name); 
VNAMES={'Draw';'Filt_Stat'};
VTYPES=[{'logical'},{cat}];
T=table('Size',[nrows,numel(VNAMES)],'VariableTypes',VTYPES,'VariableNames',VNAMES);    % empty t
T.Draw=repmat({true},nrows,1);
ct=cell(1, numel(name));
ct(:) = {cat{2}};
T.Filt_Stat=ct';
app.Portfolio_UITable.Data=T; 

i get this error:

Error using table

Specify variable types as a string array or a cell array of character

vectors, such as ["string", "datetime", "double"].

cat=categorical({'Fil';'Stat'});

That is categorical.

VTYPES=[{'logical'},{cat}];

That is a cell array that includes an element that is categorical.

T=table('Size',[nrows,numel(VNAMES)],'VariableTypes',VTYPES,'VariableNames',VNAMES);    % empty t

VTYPES is a cell array that includes an element that is categorical. The VariableTypes parameter must be one of:

• a string array
• a cell array of character vectors

The result of categorical({'Fil';'Stat'}) is categorical, not a character vector.

When you set the VariableTypes, you can set an entry to be "categorical" or 'categorical' but you cannot set the entry to be a categorical

See the documentation at https://www.mathworks.com/help/matlab/ref/table.html#d126e1778555

The VariableTypes parameter cannot hold any information about the details of categoricals.

What you might be thinking of is uitable . uitable() can have a ColumnFormat property, an element of which can be a cell array of character vectors that list category entries.

I already solved it thanks
