I have a table with data and in last column in each row is fa-trash-o icon which needs just to be shown when its hovered and also to delete that row when is clicked on it.
I made part for deleting row working and also for disappearing, but both function in combination doesn't work

What I have tried:

Here is my code:

HTML

<tr>
    <td class="tg-98kr">Libby Folfax</td>
    <td class="tg-98kr">folfax2014@example.com</td>
    <td class="tg-98kr">City</td>
    <td class="tg-98kr">Sometimes</td>
    <td class="tg-98kr">Mon, Tue, Wed</td>
    <td class="tg-98kr">13/08/2018 11:29AM</td>
    <td class="tg-98kr"><a href=""><button type="button" onclick="deleteRow(this)" class=" w3-button" style=" hover:display"></button></a></td>
  </tr>
  <tr>
    <td class="tg-q3hw">Nick Dean</td>
    <td class="tg-q3hw">nickd@example.com</td>
    <td class="tg-q3hw">City</td>
    <td class="tg-q3hw">Always</td>
    <td class="tg-q3hw">Fri, Sat</td>
    <td class="tg-q3hw">13/08/2013 11:29AM</td>
    <td class="tg-q3hw"><a ><button type="button" onclick="deleteRow(this)"  class=" w3-button " style=" hover:display">^__i class="fa fa-trash-o"></button></a></td>
  </tr>
</table>
</section>

JavaScript

<script>
function deleteRow(btn) {
  var row = btn.parentNode.parentNode;
  row.parentNode.removeChild(row);
}
</script>

CSS

table a{
   display: none;
}
table tr:hover a{
    display: block;
}

Well... I don't know why you're wrapping your buttons in anchor tags, nor the inline styles, but they don't help as far as this is concerned - anyway this works for me:

CSS

<style type="text/css">
table input{
   display: none;
}
table tr:hover input{
    display: block;
}
    </style>

HTML

<table>
<tr>
    <td class="tg-98kr">Libby Folfax</td>
    <td class="tg-98kr">folfax2014@example.com</td>
    <td class="tg-98kr">City</td>
    <td class="tg-98kr">Sometimes</td>
    <td class="tg-98kr">Mon, Tue, Wed</td>
    <td class="tg-98kr">13/08/2018 11:29AM</td>
    <td class="tg-98kr"><input type="button" onclick="deleteRow(this)" class="w3-button"  value="delete" /></td>
  </tr>
  <tr>
    <td class="tg-q3hw">Nick Dean</td>
    <td class="tg-q3hw">nickd@example.com</td>
    <td class="tg-q3hw">City</td>
    <td class="tg-q3hw">Always</td>
    <td class="tg-q3hw">Fri, Sat</td>
    <td class="tg-q3hw">13/08/2013 11:29AM</td>
    <td class="tg-q3hw"><input type="button" onclick="deleteRow(this)"  class="w3-button" value="delete" /></td>
  </tr>
</table>

JavaScript

<script type="text/javascript">
       function deleteRow(btn) {
          var row = btn.parentNode.parentNode;
          row.parentNode.removeChild(row);
       }
    </script>
