Can columns of a data table be sorted? not content of a column

Say I have a datatable DT, I have 4 columns a, b, c & d. I have four user u1,u2,u3 & u4. I want to show the se columns as per user like -

for u1 => a b c d
for u2 => b c d a
for u3 => c d a b
for u4 => d a b c

Actually I want a dynamic sorting for DT columns as per user preference.

I am using rails 3. Any help will be appreciated! Thanks
