<style>

 <tr>
  <th>Row Id</th>

</table>
<br>      
<input type="text" placeholder="Enter Row id:" id="rowId">
<br><br>  
<button onclick="deleteRow()">Delete Row</button>

function deleteRow()
{
    var id = document.getElementById('rowId').value;
    var row = document.getElementById(id);
    if(row)
    {
     row.remove();
    }
    else
    {
    alert("Please Enter Correct Row Id!");
    }
