how to define a new variable in a table

I have a table

date temperature
1/1/2020   10
1/2/2020   20
1/3/2020   30

I want to define a variable 'even' that takes a value of 1 if the day is the even number and 0 if the day is the odd number. That is,

date temperature even 
1/1/2020   10    0
1/2/2020   20    1
1/3/2020   30    0

Please advise.

TablE.even = [0; 1; 0]

The above one is an example. I want to understand how to write a if else to define a varaible in a table like, assuming test is the table name,

if day(test.date) == even
     test.even == 1
else
    test.even ==0
end

DO NOT USE table as a variable name.

TablE.even = day(TablE.date) == evem

Thank you. I have corrected errors. Still, I want to understand, in a more general example, how to define a new variable in a table using if else. Thank you.

[madhan ravi]

TablE.even = false(size(TablE.date));
for k = 1:numel(TablE.date)
TablE.even(k) = day(TablE.date(k)) == evem;
end

Thank you. What is the difference between size(TablE.date) and numel(TablE.date)?
