A = [1 2 3; 2 3 4; 3 5 6]
A =
1 2 3
2 3 4
3 5 6
A(:,3)=A(:,2)
A =
1 2 2
2 3 3
3 5 5
Eliah, I have noticed you have asked a few questions, however have never selected an answer as accepted. This would be helpful for the community as it makes helpful solutions stand out, which could then help other people who are facing the similar issues.

The above will not work exactly as written for a table() object. However you can use
A{:,3} = A{:,2};

Are you sure that you are using a table() object and not a cell array or numeric array? And are you sure that your table object has three columns already?

Finnaly there is a working code. Probably re you right and was I working with a cell array. I have changed a lot of things untill it worked. Trail and error.

If you have the latest version (R2018a), you can simply do it by movevars function, like:
yourTable = movevars(yourTable,2,'After',3);
