How to center an arrow in a table cell?

I would like to center the arrow on each cell, but I can't do it.

.positive-arrow:before {
     content: "";
     border-style: solid;
     border-width: 5px 5px;
     border-color: transparent transparent #0dff00 transparent;
}

I tried with position: absolute; left: 65%;, but it's diy....

.positive-arrow:before {
     content: "";
     border-style: solid;
     border-width: 5px 5px;
     border-color: transparent transparent #0dff00 transparent;
     position: absolute; 
     left: 65%;
}

Do you know a better solution in CSS, please?

Thank you

.w5 {
  width: 5%;
}


.w30 {
  width: 30%;
}

.positive-arrow:before {
     content: "";
     border-style: solid;
     border-width: 5px 5px;
     border-color: transparent transparent #0dff00 transparent;
}
 .negative-arrow:before {
     content: "";
     border-style: solid;
     border-width: 5px 5px;
     border-color: #f00 transparent transparent transparent; 

}

You need to make your pseudo elements inline block and then if you want to horizontally center them, change the class on the td to text-center (instead of text-end). If you want to vertically center them, then you need to add vertical align middle to the td

.w5 {
  width: 5%;
}

.w30 {
  width: 30%;
}

.positive-arrow:before {
  content: "";
  display: inline-block;
  border-style: solid;
  border-width: 5px 5px;
  border-color: transparent transparent #0dff00 transparent;
}

.negative-arrow:before {
  content: "";
  display: inline-block;
  border-style: solid;
  border-width: 5px 5px;
  border-color: #f00 transparent transparent transparent;
}

.vertical-center {
  vertical-align: middle;
}

    <tr>

      <td>EuroNext</td>
      <td class="text-end">14 379,93</td>

    </tr>
  </tbody>
</table>
