Input text box and width 100% - html

Question

I'm writing a simple form for sending some data to a database.
I use it in my own company so I don't need to have a perfect style.
I am using a table for the layout (this is okay in this application).
<table width="500px" style="border:1px solid black; overflow:hidden">
<tr>
<td>Born <input type="text" name="nato_pf" /></td>
</tr>
</table>
I would like to set the width of the input text to 100% (to the end of the line) , but, if I do that, the input text wraps to a new line.
I have found solutions only using div and they are not for me at the moment.
EDIT: Sometimes I have two input (with different sizes) on the same line, so I think I cannot add other td tags.

table {
border:1px solid black;
width: 200px;
}
.left {
float: left;
}
.left2 {
overflow: hidden;
padding: 0 4px;
}
.left2>input {
width: 100%
}
<table>
<tr>
<td>
<label class="left">Born</label>
<div class="left2">
<input type="text" name="nato_pf" />
</div>
</td>
</tr>
</table>

Answer 2

<table width="500px" style="border: 1px solid black; verflow: hidden">
<tr>
<td style="width: 50px;">
Born
</td>
<td>
<input type="text" name="nato_pf" style="width: 99%;" />
</td>
</tr>
</table>
99% of width because with 100% the textbox goes over the table's border :)
and also give a width to the first td ;)

Answer 3

you can define another td element
<table width="500px" style="border:1px solid black; overflow:hidden">
<tr>
<td>Born </td><td><input type="text" name="nato_pf" /></td>
</tr>
</table>
css
input{
width:99%;
}
