My Contact Form have a lines between the fields to fill

Hi everyone,

It has lines between the fields to fill in and I don’t know how to remove it.
Does anyone know how to eliminate the lines that are between the fields to fill.
I enclose the code of the form, among the fields to fill in:

<div>
<p><span style="font-style:italic; color:grey; padding-bottom: 20px; padding-top: 20px;">Atención: Todos los campos con * son obligatorios.</span></p>
</div>

<table class="formulario">
<tr>
<td class="formulario">Nombre<span style="color:#CE9108; text-style:bold;">*</span>:</td>
<td class="formulario">[text* your-name]</td>
</tr>
<tr>
<td class="formulario">Email<span style="color:#CE9108; text-style:bold;">*</span>:</td>
<td class="formulario">[email* your-email]</td>
</tr>
</tr>
<tr>
<td class="formulario">Empresa<span style="color:#CE9108; text-style:bold;">*</span>:</td>
<td class="formulario">[text* your-empresa]</td>
</tr>
<tr>
<td class="formulario">Teléfono<span style="color:#CE9108; text-style:bold;">*</span>:</td>
<td class="formulario">[tel* tel-190]</td>
</tr>
<tr>
<td class="formulario">Mensaje<span style="color:#CE9108; text-style:bold;">*</span>:</td>
<td class="formulario">[textarea* your-message]</td>
</tr>
<tr>
<td class="formulario">Política de privacidad (required)<span style="color:#CE9108; text-style:bold;">*</span>:</td>
<td class="formulario">[checkbox* your-country use_label_element "ACEPTAR"]</td>
</tr>
<tr>
<td class="formulario"></td>
<td class="formulario"><p style="line-height: 24px;">[submit id:envio "Enviar"]</p></td>
</tr>
</table>
