//if you have $id is table_a primary key id then you can get by this:
//controller
function detail($id){
$data=array();
$this->load->model('model_name');
$table_a_data= $this->model_name->get_table_a_by_id($id);
$data['steve']=$this->model_name->get_steve_by_name($table_a_data->name);
$this->template->display('test/detail',$data);
  }

//model
function get_table_a_by_id($id){
return $this->db->where('id',$id)->get()->row_array();
}
function get_steve_by_name($name){
return $this->db->where('name',$name)->get()->result_array();
}

//if you don't have id then use join to get data
