javascript - How can I get the value from a cell in a table?

I have read all the related posts and used them with no success. Obviously I'm not a javascript expert. I had tried with option, and selectedItem, but don't know how to extract the select object to use it.

This is a fraction of my code, I hope you can help me.

<div class="card-body">
  <table class="table" id="products_table">
    <thead>
    <tr>
      <th>Descripci??n</th>
      <th>Suaje</th>
      <th>Cantidad/etiq.</th>
      <th>Importe</th>
      <th>Sustrato</th>
      <th>Sustrato $</th>
      <th>Acabado</th>
      <th>Acabado $</th>
      <th>Otros</th>
      <th>Otro $</th>
      <th>Colores</th>

    </tr>
    </thead>
    <tbody>

    <input type="text" id="test" name="test" class="form-control"/>

    <tr id="product0">


      <td>
        <input type="text" name="descripcion" class="form-control" value=""/>
      </td>
      <td>
        <select id="suajes_lista" name="suajes_lista" class="form-control" style="width: 100px;">
          <option value="">-- escoge el suaje --</option>
          @foreach ($suajes as $suaje)
            <option value="{{ $suaje->id }}">
              {{ $suaje->codificacion . ', Corte '. $suaje->corte->nombre. ', Dientes '. $suaje->dientes . ', M. Eje '. $suaje->medida_eje . ', M. Desarrollo '. $suaje->medida_desarrollo . ', C. Eje '. $suaje->no_cavidades_eje . ', C. Desarrollo '. $suaje->no_cavidades_desarrollo . ', Sep. C. Eje '. $suaje->sep_cavidades_eje. ', Sep. C. Desarrollo '. $suaje->sep_cavidedes_desarrollo . ', P. Dist. '. $suaje->porcentaje_dist . ', Ancho mm '. $suaje->ancho_papel_mm . ', Mult. ' . $suaje->mult_venta_millares
              }}
            </option>
          @endforeach
        </select>
      </td>
    </tr>
    </tbody>
  </table>
</div>
