Concatenation error while defining a cell variable

I am trying to define a cell variable as

col_req = {'columnA', 'ColumnB',
                'ColumnC'}

and i get the following error. I don't understand why changing line in code causes this error? If cell values are more I can't fit them in one line causing readability issue.

            Dimensions of matrices being concatenated are not consistent.

col_req = {'columnA', 'ColumnB', 'ColumnC' }

OR

col_req = {'columnA', 'ColumnB',........
           'ColumnC' }

@KSSV what is the purpose of ...... can you explain?

It is to continue your code to next line.
