Hello, so I got a table called zoom, with 4 columns, and I assign a name for each column

zoom = [tempo_novo variavel_novo]; % table
zoom.Properties.VariableNames = {'data','ananas','morango','nutella'};

The problem is now I just want to work with the 2nd, 3rd and 4th column but I want to keep their name. is that possible? And my idea of converting from a table to an array is when I have equations to do I can use "()" instead of "{}" to call the values.

 experiencia = table2array(zoom(:,2:end)); % double
  experiencia.Properties.VariableNames = {'ananas','morango','nutella'};

table2array converts the table to an array, but arrays do not have names for the columns. Only tables contain such names. Therefore you have to decide if you want to work with the table object or with an array.

Tiago, again, I really recommend that you look at the documentation for table subscripting. You will likely find that dot subscripting solves your problem.
