I fix it,
the problem is JS library rend cover

//cdn.datatables.net/select/1.3.1/js/dataTables.select.min.js
must be place the last position than some other hand select library .
e.g.
//gyrocode.github.io/jquery-datatables-checkboxes/1.2.12/js/dataTables.checkboxes.min.js

//cdn.datatables.net/select/1.3.1/js/dataTables.select.min.js
must be place the last position than some other hand select library .

it's work for me
