1. Create the full table first, however you were going to create it:
name = {'Joe'; 'Elisa'; 'John'};
age = [30; 10; 25];
weigth = [100; 150; 180]; %note that weigth is mispelled, should be weight
t = table(name, age, weight)
2. use logical indexing to select the columns you want:
selected = [1, 0, 1];
selected = logical(selected);
%or create it directly as logical:
%selected = [true, false, true];
filteredtable = t(:, selected) %only keep selected columns
