I have a table T

Date City Visitors
----------------------
1/1/2020 New York 10
1/2/2020 New York 20

I want to add a variable 'state' that looks like

Date City Visitors State 
----------------------
1/1/2020 New York 10 NY
1/2/2020 New York 20 NY

I did

state=strings(height(T),1)

then

state(:) = 'NY'

then I create a table and merged. But is there a simpler way?

T.newVar(:,1)=state;

Please ensure that state have same length as T, else you may have to use repmat

But then you have to substiute a value 'state'?
