How to display a table without it showing "var1"?

x = datetime(2021,1,1) + caldays(0:4);
e = [1,6,3,2,8;4,5,6,7,7;2,4,7,8,6;]

e = 3×5

1 6 3 2 8 4 5 6 7 7 2 4 7 8 6

disp(x)

   01-Jan-2021   02-Jan-2021   03-Jan-2021   04-Jan-2021   05-Jan-2021

t = table(x',e')

t = 5×2 table
       Var1           Var2    
    ___________    ___________

    01-Jan-2021    1    4    2
    02-Jan-2021    6    5    4
    03-Jan-2021    3    6    7
    04-Jan-2021    2    7    8
    05-Jan-2021    8    7    6

b = t(sum(e)' == max(sum(e))',1)

b = table
       Var1    
    ___________

    05-Jan-2021

tstring = evalc('disp(b)')

tstring = 
    '       Var1    
         ___________
     
         05-Jan-2021
     
     '

disp(['test',num2str(tstring),' end of test.'])

test       Var1    
    ___________

    05-Jan-2021

 end of test

I want to display it like this:

"test 05-Jan-2021 end of test."

And is there a way that i can get 5 as an variable so i can use it in other formula's?

Thanks for taking a look at my question!

Tables are a container class: they contain data of other classes. So it is very important to distinguish between the table itself (or a subtable of it) which is a container, and the data store within the table. How to refer to parts of the table itself (i.e. to the container) vs. how to refer to its contents (e.g. numeric, text, datetime, etc.) is explained here:

https://www.mathworks.com/help/matlab/matlab_prog/access-data-in-a-table.html

Instead of trying to refer to a table itself you need to refer to the content of the table, e.g. using indexing with curly braces or by using the variable/column name:

x = datetime(2021,1,1) + caldays(0:4).';
e = [1,6,3,2,8;4,5,6,7,7;2,4,7,8,6].';
t = table(x,e)

t = 5×2 table
         x              e     
    ___________    ___________

    01-Jan-2021    1    4    2
    02-Jan-2021    6    5    4
    03-Jan-2021    3    6    7
    04-Jan-2021    2    7    8
    05-Jan-2021    8    7    6

v = sum(t.e,2)

v = 5×1

7 15 16 17 21

y = max(v)==v

y = 5×1 logical array
   0
   0
   0
   0
   1

sprintf('test %s end of test.',t.x(y))

ans = 'test 05-Jan-2021 end of test.'

"And is there a way that i can get 5 as an variable so i can use it in other formula's?"

Either:

d = day(t.x(y))

d = 5

d = t.x(y).Day

d = 5
