MATLAB: Create dataset with a pre-filled text column,got a weird relut

dataset cell string text repmat

Hello, All
I am using the following code to create a dataset:
    my_dataset=cell(5,1); 
    my_dataset=cell2dataset([{'Variable_1'};my_dataset]);
    my_dataset.Variable_1=repmat('some_string',5,1);
However, the result is weird: instead of a continuous text string, it is a combination of individual characters (shown below)
    '''s'''  '''o'''  '''m'''  '''e'''  '''_'''  '''s'''  '''t'''  '''r'''  '''i'''  '''n'''  '''g'''
    '''s'''  '''o'''  '''m'''  '''e'''  '''_'''  '''s'''  '''t'''  '''r'''  '''i'''  '''n'''  '''g'''
    '''s'''  '''o'''  '''m'''  '''e'''  '''_'''  '''s'''  '''t'''  '''r'''  '''i'''  '''n'''  '''g'''
    '''s'''  '''o'''  '''m'''  '''e'''  '''_'''  '''s'''  '''t'''  '''r'''  '''i'''  '''n'''  '''g'''
    '''s'''  '''o'''  '''m'''  '''e'''  '''_'''  '''s'''  '''t'''  '''r'''  '''i'''  '''n'''  '''g'''
The result I am looking for should be like following:
some_string
some_string
some_string
some_string
some_string
How should I change my code to get the correct result? Thanks!

ok, I figured it out by myself. In case someone has similar question, here is the right code:
my_dataset=cell(5,1); 
my_dataset=cell2dataset([{'Variable_1'};my_dataset]);
my_dataset.Variable_1=repmat({['some_string']},5,1);
