This is possible using a slight variation of the cyclist's initial approach.
% Sample data
A = magic(4);
% Create the table to which you want to add data
T = array2table(A, 'VariableNames', {'first', 'second', 'third', 'fourth'})
% Define the new variable and the data it should contain
newvariable = 'fifth';
x = [20; 17; 8; 2];
% Add the new variable to the table T
T.(newvariable) = x

% Create the table
x = rand(3,1);
tbl = table(x);
% Create the string that contains the variable name
varString = 'x';
% Access that variable, using the string
tbl(:,varString)

This is also possible:
% Create the string that contains the variable name
varString = {'velocity'};
% Create the table with the name
x = rand(3,1);
tbl = table(x,'VariableName',varString);
