How can I change value in a table?

I have this code

d={'first';'second';'third';'forth'};
L=[2;35;4;65];
T=table(d,L)

after the result came,I would like to change the 35 to zero. How can I change the table value?

Adding to Star's way, here are some other ways:

T{2, 2} = 0  % Set row 2, column 2 to 0.
T.L(2)  = 0  % Set row 2 of column "L" to 0 (L not required to be column #2 in this case)

It depends on what you know about the 35. Star's way will set all values of 35 in column "L" to zero. The ways I gave are if you know that it's row 2 in column 2 (the "L" column), and it's row 2 you want to set, instead of all the rows with a value of 35.

It can be tricky figuring out when to use braces, parentheses, or brackets in MATLAB. Tables are sort of like cell arrays in a way, it's just that every item in a column must be of the same type. So the FAQ http://matlab.wikia.com/wiki/FAQ#What_is_a_cell_array.3F may help you to figure out when to use braces, parentheses, or brackets.

One approach:

d={'first';'second';'third';'forth'};
L=[2;35;4;65];
T=table(d,L)

idx = find(L == 35);
T.L(idx) = 0

T =

    4×2 table

         d        L 
      ________    __

      'first'      2
      'second'    35
      'third'      4
      'forth'     65

T =

    4×2 table

         d        L 
      ________    __

      'first'      2
      'second'     0
      'third'      4
      'forth'     65

Thank you very much.

I want to make the change deponent on the location not for a specific value. maybe there are more than on values = 35 but I want to change (1,2) only

Easy enough:

T.L(2) = 0;
