Index into a table using a vector of values

Suppose I have a table:

T = 
  var1   var2
  a      1
  b      2
  c      2
  d      3
  e      4
  f      4
  g      4

and I am interested in the rows of T where var2 takes values 1, 3, or 4. Is there a direct way to subset into the table using the vector [1; 3; 4], instead of using a for-loop? To be clear, I am interested in obtaining the following output:

subT = 
  var1   var2
  a      1
  d      3
  e      4
  f      4
  g      4

I don't see how I can get this using a logical expression. Any thoughts?

A=[5  1;7 3;12 4;47  4;6   4]
out=A(ismember(A(:,2),[1 3 4]),:)

Thanks Azzi, that makes sense! Your code is written for arrays -- for tables, I would do something like this:

vec = [1; 3; 4];
rows = ismember(T.var2, vec);
subT = T(rows,:);
