Ubah tampilan dari baris menjadi kolom dengan foreach, tapi nama alternatif satu yang muncul

maaf master dari kemarin ini belum kepecahkan juga.

ini controller nya

public function index()
	{
		$this->load->model('model_alternatif_kriteria');
		$data['tabelalternatifkriteria'] = $this->model_alternatif_kriteria->getdata();
		$this->load->model('model_alternatif');
		$data['tabelalternatif'] = $this->model_alternatif->getdata();
		$this->load->model('model_kriteria');
		$data['tabelkriteria'] = $this->model_kriteria->getdata();
		$data['content'] = 'view_alternatif_kriteria';
		$this->load->view('admin/template_admin', $data);
	}

ini modelnya

public function getdata()
	{
		$this->db->select('*');
		$this->db->from('alternatif_kriteria');
		$this->db->join('alternatif', 'alternatif.id_alternatif=alternatif_kriteria.id_alternatif');
		$this->db->join('kriteria', 'kriteria.id_kriteria=alternatif_kriteria.id_kriteria');
		return $this->db->get()->result();
	}
	public function selectdata($id)
	{
		$this->db->where('id_alternatif_kriteria', $id);
		return $this->db->get('alternatif_kriteria')->row();
	}

	public function select_alternatif_kriteria($id_alternatif, $id_kriteria)
	{
		$this->db->where('id_alternatif', $id_alternatif);
		$this->db->where('id_kriteria', $id_kriteria);
		return $this->db->get('alternatif_kriteria')->row();
	}

ini viewnya

<div style="overflow-y: auto;">
        <table class="table table-hover table-bordered" id="example">
           <thead>
              <tr>
