Trying to change cells in a table

I have a small test table and I try to replace a column (or row) with the same size string. I just get NaN out of it. I would like to replace the table colum from (1,2,3,4,5) to type_1, type_2 etc. where the column names are in a 5x1 string. How can I do this? And how would it change for rows as well? Thanks

try this:

Column1Names={'type_1';'type_2';'type_3';'type_4';'type_5'};
% making another table
LastName = {'Sanchez';'Johnson';'Li';'Diaz';'Brown'};
Age = [38;43;38;40;49];
Height = [71;69;64;67;64];
Table2 = table(LastName,Age,Height)

Table2 = 5×3 table
     LastName      Age    Height
    ___________    ___    ______

    {'Sanchez'}    38       71  
    {'Johnson'}    43       69  
    {'Li'     }    38       64  
    {'Diaz'   }    40       67  
    {'Brown'  }    49       64  

Table2.LastName=Column1Names

Table2 = 5×3 table
     LastName     Age    Height
    __________    ___    ______

    {'type_1'}    38       71  
    {'type_2'}    43       69  
    {'type_3'}    38       64  
    {'type_4'}    40       67  
    {'type_5'}    49       64  

Or

Table2(:,1)=Column1Names

Table2 = 5×3 table
     LastName     Age    Height
    __________    ___    ______

    {'type_1'}    38       71  
    {'type_2'}    43       69  
    {'type_3'}    38       64  
    {'type_4'}    40       67  
    {'type_5'}    49       64
