you can use query business rule on your table, get the groups to which logged in user belongs and then apply the query
Something like this
(function executeRule(current, previous /*null when async*/) {
// Add your code here
var groups = new global.ArrayUtil().convertArray(gs.getUser().getMyGroups());
current.addQuery('assignment_group','IN', groups.toString());
})(current, previous);
