f = figure('Position', [100 100 752 250]);
t = uitable('Parent', f, 'Position', [25 50 700 200]);
t.ColumnName = {'Num1','Num2','Text'};
t.Data = {'b', 'q','JN'};
t.ColumnEditable=[true,true,true];
ret=categorical({'H';'L'});
t.ColumnFormat ={'bank' ret 'bank'};
Error setting property 'ColumnFormat' of class 'Table':
ColumnFormat definitions must be either 'numeric', 'logical', 'char', or be a popupmenu definition
Error in CANCELLA (line 10)
t.ColumnFormat ={'bank' ret 'bank'};

You can't set the ColumnFormat value to be a categorical. It must be either 'numeric', 'logical', 'char', or be a popupmenu definition (character array).
Why not just do this?
f = figure('Position', [100 100 752 250]);
t = uitable('Parent', f, 'Position', [25 50 700 200]);
t.ColumnName = {'Num1','Num2','Text'};
t.Data = {'b', 'q','JN'};
t.ColumnEditable=[true,true,true];
ret={'H' 'L'};
t.ColumnFormat ={'bank' ret 'bank'};
Not sure what you want the 'bank' values to be. If you meant 'blank', use [] instead.
t.ColumnFormat ={[] ret []};
If you meant to have them be dropdown menu uptions for the first and third column, do this.
t.ColumnFormat ={{'bank'} ret {'bank'}};

it give me an error :
Error setting property 'ColumnFormat' of class 'Table':
ColumnFormat definitions must be either 'numeric', 'logical', 'char', or be a popupmenu definition
Error in CANCELLA (line 12)
t.ColumnFormat ={[] ret []};
i want to have dropdown menu only the second element in table (the first and the third are blank)

What version of MATLAB are you using?
Even simpler approach would be this:
f = figure('Position', [100 100 752 250]);
t = uitable('Parent', f, 'Position', [25 50 700 200]);
t.ColumnName = {'Num1','Num2','Text'};
t.Data = {'b', 'q','JN'};
t.ColumnEditable=[true,true,true];
t.ColumnFormat ={[] {'H' 'L'} []};

>> version
ans =
'9.14.0.2254940 (R2023a) Update 2'
t.ColumnFormat ={[] {'H' 'L'} []};
no ...i want to use categorical because i import it from function..(there is a lot data)
this is an example but my progect is different

Again, you can't use categoricals. It must be a char. If your data coming in is categorical, you must extract the categories and use that to set the ColumnFormat.
May something like this?
f = figure('Position', [100 100 752 250]);
t = uitable('Parent', f, 'Position', [25 50 700 200]);
t.ColumnName = {'Num1','Num2','Text'};
t.Data = {'b', 'q','JN'};
t.ColumnEditable=[true,true,true];
ret=categorical({'H';'L'});
cat = categories(ret);
t.ColumnFormat ={[] {cat{:}} []};
