day           temperature
1/1/2020      30
I want to create a vaiable 'month" from 'day' and put it next to 'day' like
day      month temperature

Please advise.

The specifics will depend on what format the variable day is. Here, I assume it is a datetime.
% Create the table
day = datetime('1/1/2020');
temperature = 30;
T = table(day,temperature);
% Derive month from day
T.month = month(day);
% Rearrange the columns
T = T(:,[1 3 2])
