Here is a mock table.
% Mock table.
headers = {'A' 'B' 'C' 'D' 'E'};
data = cell(4,5);
T = cell2table(data);
T.Properties.VariableNames = headers;
I am trying to add four new columns at the beginning of T where each column contains the respective workspace variable across all rows.
par = "p00";
type = "Pilot";
trial_no = 1;
vel = "Moderate";
I'm a bit stuck on how to do this, so will appreciate any help.
Thank you.

You can use 'Before' and 'after' to add the variables into a particular location in the table.
Note: you will need to supply values for all of the rows at the time you add the variables.
Much of the time it is easier to do something like
T.par = appropriate values
T.type = appropriate values
T.trial_no = appropriate values
T.vel = appropriate values
T = T(:,{'par', 'type', 'trial_no', 'vel', headers{:}});
which is to say, add the variables one by one, and then afterwards re-order the variables to the final order.
