I have the following problem, I have a table that is filled with several arrays that when clicking on a button the values are moved to another table, so far so good, the problem is when I want to remove the values (there is a button in each row of the table) when clicking on a value I can delete, but if there are 3 elements and I eliminate the first one, the table stays with a width (length) of 0 it is as if I deleted all the following records, so if I delete the 2nd record the following ones are eliminated, I leave part of the code:

<script type="text/javascript">

        var cont=0;
        var total=0;
        var arr_canti=[];
        var arr_id_bodega_producto=[];
        var arr_precio = [];
        var arr_subtotal = [];
        var v_id_bodega_producto = 0; 
        var v_producto =  "";
        var v_existencia = 0;
        var v_pre1 = 0;
        var v_pre2 = 0;
        var v_pre3 = 0;
        var v_pre4 = 0;
        var v_pre0 = 0;
        var v_canti = 0;
        var v_precio = 0;
        var v_id_del = 0;
    $(document).ready(function(){
        $('.agregar_fila').click(function(){
            document.getElementById('caja3').style.display='block';

            v_id_bodega_producto = $(this).parent().parent().find('input#val_id_bodega_producto').attr('value'); 
            v_producto =  $(this).parent().parent().find('input#val_producto').attr('value');
            v_existencia = parseInt($(this).parent().parent().find('input#val_existencia').attr('value'));
            v_pre1 = $(this).parent().parent().find('input#val_pre1').attr('value');
            v_pre2 = $(this).parent().parent().find('input#val_pre2').attr('value');
            v_pre3 = $(this).parent().parent().find('input#val_pre3').attr('value');
            v_pre4 = $(this).parent().parent().find('input#val_pre4').attr('value');
            v_pre0 = $(this).parent().parent().find('input#val_pre_farm').attr('value');


            $('#pre_producto').val(v_producto);

The problem is that you are removing the entire <td>Datos</td> tag.
If you have a 3x3 table and you eliminate one of the tables the table loses its structure.
To empty said cell, you only need to empty the value:

//Con esto vacias completamente la celda
$(this).html("");

//Con este estableces el 0 como dato de la celda
$(this).html("0");

This way you do not delete the cell but only its value

DEMO

$(document).ready(function(){
 // Vacia la columna
  $("tr:nth-child(1)>td").click(function(){
      $(this).html("");
  });
  // Establece el valor a 0
  $("tr:nth-child(2)>td").click(function(){
      $(this).html("0");
  });
  // Escribe vacio
  $("tr:nth-child(3)>td").click(function(){
      $(this).html("vaciado");
  });
});

table,tr,td{
   border:1px solid black;
   border-collapse: collapse;
   cursor:pointer;
}
td{
   padding:5px;
   width:60px;
   text-align:center;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table>
      <tr>
        <td>Dato</td>
        <td>Dato</td>
        <td>Dato</td>
      </tr>
      <tr>
        <td>Dato</td>
        <td>Dato</td>
        <td>Dato</td>
      </tr>
      <tr>
        <td>Dato</td>
        <td>Dato</td>
        <td>Dato</td>
      </tr>
   </table>

Thanks for the comments, maybe for more explanation, I do not just want to delete the value, I store the values in an array and then I show them in inputs (this is optional but if I want them in a table) then apart from removing the value in the array, I need to remove its respective row (with everything and td)
